Opal widespread on Martian terrain and astroengineering

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Life - Opal, a mineral that needs water to form, is widespread in Martian terrain younger than 2.5 billion years old, new spacecraft observations suggest. The discovery offers the most recent mineralogical evidence yet of liquid water on the planet's surface – and suggests an intriguing new target for future searches for Martian life. See article.
g Intelligence -Human evolution, Chicago researchers report, is still under way, in what has become our most important organ: the brain. In two related papers published in Science, they show that two genes linked to brain size are rapidly evolving in humans. The researchers looked at variations of microcephalin and ASPM within modern humans, and found for each gene one class of variants has arisen recently and has been spreading rapidly because it is favored by selection. See article. Note: This article is from 2005.
g Message -What is astroengineering, and how might it help us determine if alien civilizations exist? See article.
g Aftermath - We humans are familiar with the back-and-forth of face-to-face contact — something we likely will not have in an interstellar conversation. The timescale of a human life may well not be enough for a meaningful dialogue with another species. Interstellar dialogue may make sense only across generations. See article.

Life preserved in Lunar craters and Hubble up and running again

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Abodes -Some lunar craters may be perfect for preserving samples of life from Earth, and possibly even from Mars or other planets. Ancient organic remnants could have been delivered to the Moon as debris that was thrown into space after asteroids impacted rocky worlds in our solar system. See article.
g Life - By the dark of the Halloween new moon, scientists are looking at what's hovering just above the ground. Far from ghost-busting, however, the researchers are using sophisticated technology like Doppler weather radar to study the aerosphere--the air and the organisms that migrate and feed within it. See article.
g Message - Book alert: Exobiology (or cosmic biology), the scientific search for life beyond Earth, "resembles a brainstorming session, with many discordant voices," according to “Here Be Dragons : The Scientific Quest for Extraterrestrial Life,” by David Koerner, Simon LeVay, a book mirroring that ferment. Koerner, a planetary scientist, and LeVay, a neuroanatomist, favor the view that technologically advanced civilizations are common in our galaxy and beyond, though many of their colleagues disagree. Their heady tour skips from "extraterrestrial environments" right here on Earth (Antarctica, Death Valley, etc.) where NASA scientists are investigating extreme environments believed to resemble conditions on other planets or moons, through the SETI Institute in California, whose radio telescopes scan the skies for transmitting civilizations, to the Bios Group, a Santa Fe start-up company that uses complexity theory to explore the intrinsic rules underlying the growth of evolving organisms or human institutions. Koerner has used the Hubble Space Telescope to study the birth of planets, and the book presents the latest evidence that planetary systems do indeed swirl around many stars besides our sun. Their open-mindedness within the establishment field of exobiology, an area that is now the "recipient of huge government resources," is manifest as they contemplate multiverse models of coexisting universes or attend a NASA workshop where astronomers, engineers and futurists discuss antimatter propulsion and laser-powered craft. Koerner and LeVay have a gift for helping the uninitiated over technical terrain, aided by clear writing, intuitive examples, color photos and drawings. See reviews.
g Cosmicus -With a visit to the Hubble Space Telescope off until next spring at the earliest, NASA today chose Nov. 14 for its next space shuttle launch, a flight by Endeavour to the international space station. See article.
g Learning -If you’re doing some basic research on evolution for a high school class project or to write a letter to the editor, a great place to start is Berkeley University’s “Evolution Wing” of its “UCMP Exhibit Hall.” These exhibits trace evolutionary thought as it has developed over time, pausing to ponder the contributions of scientists and thinkers including Aristotle, Darwin and Wallace.
g Aftermath - One of our natural tendencies when we make contact with strangers is to try to impress them. Sloppy dressers might polish their shoes for a job interview, hopeful suitors will wash their cars for a first date and prospective children-in-law will be on their best behavior in the presence of the parents of their intended. Wouldn’t we want to do the same in our first contact with ET? Lewis Thomas, in his book “Lives of a Cell,” suggests that if we want to impress an alien civilization, we should send "Bach, all of Bach, streamed out into space, over and over again." See article. Note: This article is from 2003..

Alien depictions in science fiction and will ET be altruistic or hostile

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Message -Fermi’s Paradox, Part I: Is there obvious proof that we could be alone in the galaxy? Enrico Fermi, an icon of physics, thought so — might he have been right? Fermi is best remembered for building a working atomic reactor in a squash court. But in 1950, Fermi made a seemingly innocuous lunchtime remark that has caught and held the attention of every SETI researcher since (How many luncheon quips have you made with similar consequence?). See article. Note: This article is from 2001.
g Imagining -Here’s an interesting Web site about alien depictions in science fiction: “Life on Other Worlds”.
g Aftermath - Will ET be altruistic or hostile? An Internet poll found a strong connection between people’s beliefs about extraterrestrials and their feelings about how meaningful life is. What makes the results even more compelling is that they match the findings of an earlier study conducted under more stringent testing conditions. See article. Note: This article is from 2002.

Titan’s electrical storms and symposium on possible nature of life on other planets

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Abodes -Scientists have determined that Saturn's moon Titan could have electrical storms occurring in its atmosphere. Such storms might provide energy for the formation of important organic and pre-biotic molecules. See article.
g Life - Western Australia's Pilbara region continues to yield tantalizing clues on the origin of Earth's life forms. See article.
g Message -Fermi’s Paradox, Part II: Could galactic empires exist? In a previous article, we noted that there has been plenty of time for aliens keen on colonizing the Milky Way to pull it off. However, we see no signs of galactic federation ("Star Trek" aside). Why does the cosmos look so untouched and unconquered? What is keeping advanced extraterrestrials from claiming every star system in sight? See article. Note: This article is from 2001.
g Learning - First-year students from UQ's Advanced Study Program in Science have organized a national symposium to explore ideas such as the origins of the universe and the possible nature of life on other planets. See article.
g Imagining -Here’s a neat Web site: The Exorarium. At the Exorarium, visitors get a chance to mix and match the same ingredients that brought about human life, shaping their own unique intelligent life forms. For example, you might start with a hot or cool star, a heavy or light planet, one with lots of water or a desert world, and so on – until a unique ecosystem takes shape before your eyes … a family tree leading to the ultimate outcome, a species of intelligent life. See article.
g Aftermath - Should we really expect extraterrestrials to be sympathetic to our pleas to be altruistic because of the symbolic kinship we might share with them? See article. Note: This article is from 2003.

Solar system analog and ‘Let’s Build and Extraterrestrial’

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Stars -A nearby solar system bears a striking similarity to our own solar system, raising the possibility it could harbor Earth-like planets. See article.
g Life - Scientists have discovered that many genes related to disease are probably as old as the very first living cell. Other disease-related genes can be traced back to important moments in evolution, such as the origin of mammals. See article.
g Message -Book alert: In “Sharing the Universe: Perspectives on Extraterrestrial Life,“ a fascinating speculative book, author Seth Shostak builds a careful case for the importance of the institute's work, narrowing the range of the galaxy's possibly life-nurturing stars and imagining what forms non-carbon-based life might take. "Although a majority of the American public is convinced that aliens are making house calls to planet Earth," Shostak writes, "most scientists aren't." In prose as lively and dramatic as the science-fiction movies he clearly savors, in the book's final chapters Shostak describes scientific reality: "If it happens, it will begin slowly and without warning in a radio telescope's cramped, cluttered, control room.... under a hundred tons of steel faced off against the pinpoint gleams of the night sky." The book is rich in considered, engaging science, with occasional lapses into excessive speculation about artificial intelligence in space, or into plugs for the institute. Sections on possible alien behavior, on motives for contact and means of contact — all of which make comparisons to movies — are compelling as they reveal as much about us as about anyone who may pop across for a visit. See review.
g Cosmicus - India has successfully launched the country's first mission to the moon. The mission also includes a large amount of international cooperation, and is carrying instruments from both the European Space Agency and NASA. See article.
g Imagining -Here’s a neat site that draws upon the history of science fiction for examples: “Let’s Build an Extraterrestrial”.
g Aftermath - If some day we decide to transmit intentional messages to the stars, rather than solely listen as current SETI programs do, what would we say? What sort of first impression would we want to give our celestial correspondents? See article. Note: This article is from 2002.

Unique magnetic fossils and Fermi’s Paradox revisited

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Life - Scientists have discovered microscopic, magnetic fossils unlike anything previously seen. The fossils were discovered in sediments along the Atlantic that were deposited during an ancient period of global-warming. See article.
g Message -Fermi’s Paradox, Part III: We seem to have the Galaxy to ourselves. At least, that’s the obvious conclusion from the apparent lack of aliens in the neighborhood. But this conclusion might be a bit too obvious, and possibly wrong. In previous articles, we’ve considered why extraterrestrial intelligence – even if common – would have restrained itself from spreading to every half-decent star system in the galaxy. It’s possible that the aliens have done cost-benefit analyses that show interstellar travel to be too costly or too dangerous to warrant ambitious colonization efforts. An alternative suggestion that would explain our apparent solitude is that the Galaxy is urbanized, and we’re in a dullsville suburb. See article. Note: This article is from 2001.
g Cosmicus -In recent years "teamwork" and "team-building" have been catchphrases of the workplace environment. For most people, however, worrying about getting along with their co-workers and working together for the common good may occupy only a small amount of their time. But what if you and your co-workers were confined to a small space, together for 24 hours a day in an inherently dangerous workplace, and unable to get away from each other because you were orbiting more than 350 kilometers above Earth? See article.
g Learning - An article in Science magazine discussing why Spore flunks various kinds of science after close scrutiny by a variety of scientists reminds me of history buffs that get hysterical when a movie is historically inaccurate. While a couple of them had a few nice things to say, Spore in general got poor marks in organismic and evolutionary biology, squeaked by with barely sufficient grades in cultural anthropology, physics, and astrobiology, and was reasonably highly rated in sociology and galaxy structuring. See article.
g Aftermath - How might interested parties envisage the design of a human team to prepare for an encounter with aliens — and improve the operational guidelines for that eventuality? See article.

Planets pulled closer to their stars and how Drake Equation numbers look today

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Abodes - Imagine a solar system where a life-bearing planet is slowly pulled in closer to its star. If life could survive the ensuing climate change, it would provide a clear example of the Gaia hypothesis in action. See article.
g Life - The way termite guts process food could teach scientists how to produce pollution-free energy and help solve the world's imminent energy crisis. Nobel laureate Steven Chu has urged scientists to turn their attention to finding an environmentally friendly form of fuel. In an impassioned plea to some of the world's brightest minds, he explained how he's leading by example and encouraged others to join the effort that "may already be too late." See article.
g Message -In 1961, astronomer Frank Drake wrote the equation that put the search for alien civilizations on a scientific footing and launched the modern SETI movement. How do the numbers look today? See article. Note: This article is from 2002.
g Cosmicus - After departing on Oct. 12 to the International Space Station, with a round-trip ticket that cost him $30 million, famed videogame creator Richard Garriott returned safely back to Earth on Friday. See article.
g Learning -One of the most frequently cited problems facing those who build and rely on space systems is a receding pool of engineering talent, a function of declining interest among young people in math and science. See article.
g Aftermath - In our everyday lives, we sometimes emulate computers, though typically without their full precision. When we do a favor for someone, more often than we’d like to admit, we keep an informal tally of who owes us, and how much. According to sociobiologists, who attempt to explain behavior in terms of its value for survival, such calculations might have a biological basis. And as we will see, they may also provide some clues to communicating with life beyond Earth. See article.

Rocky planets staying hot and aftereffects of contact between two alien civilizations

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Abodes - Astronomers have determined that young, rocky planets stay hot longer than previously believed. The heat generated by these planets could make them easier to spot around distant stars. See article.
g Life - Fossils from an organism known as the 'fishapod' are helping scientists understand how life moved out of the sea and began to walk on dry land. The study is providing new insights about this important step in the evolution of life on Earth. See article.
g Message -Interstellar transmissions via energy-markers (photons) or matter-markers (probes) appear to be energetically indistinguishable alternatives for advanced technical societies. Since only Type II and Type III civilizations realistically can afford beacons or star probe technology, alternative distinguishability criteria suggest the possible superiority of intelligent artifacts for contact and communication missions among extraterrestrial cultures. A balanced, more cost-effective Search for Extraterrestrial Intelligence strategy is needed. See article.
g Cosmicus - The ailing Hubble Space Telescope could be snapping pictures of the heavens again as early as Saturday after engineers fixed one of the problems that has largely shut down the instrument for the last three weeks. See article.
g Learning -Unfortunately, the controversy over the theory of evolution continues even as science offers all people a way to know about the natural world and how it works.. See article. Note: This article is from 2003.
g Aftermath - Among scientists involved in the Search for Extraterrestrial Intelligence, it’s quite common to be focused on the future, ever mindful that it could take years, or even decades, to find a signal from otherworldly intelligence. But if historian Steve Dick has his way, astronomers will also turn their attention toward the past as they search for life beyond Earth — to discover the aftereffects of contact between two intelligent cultures. See article. Note: This article is from 2003.

Mars exploration tested and alien disinformation

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Message -A number of searches for extraterrestrial intelligence actually have occurred, are ongoing and are planned. Here’s one of the more famous ones: Project BETA, at Harvard University. See article.
g Cosmicus -When humans are sent to Mars, will they survive the journey? People confined to close quarters for a long time inevitably get on each others nerves, and the fact that Mars is named after a god of warfare seems a bad omen. The Mars Society sent seven people to Devon Island to see if we can’t all just get along for the sake of exploration. See article.
g Learning -Are we alone? Are humans unique in the universe, or is our existence the natural outcome of universal processes that produced complex life on Earth and elsewhere? As we observe the universe beyond Earth, we find that we are fundamentally a part of it. To understand the relationship of humanity to stardust requires understanding evolution in its broadest sense. See article. Note” This article on teaching evolution in schools is from 2001.
g Aftermath - Could a signal from the stars broadcast by an alien intelligence also carry harmful information, in the spirit of a computer virus? Could star folk launch a "disinformation" campaign — one that covers up aspects of their culture? Perhaps they might even mask the "real" intent of dispatching a message to other civilizations scattered throughout the cosmos. See article.

‘Mars Life’ and physics of alien civilizations

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Intelligence -Chimpanzees want to be just like their friends, at least when it comes to getting food. The social conformity displayed in a new study is a trait previously seen only in humans. See article.
g Message -Current searches for extraterrestrial life focus on detecting electromagnetic waves, mainly via radio. Here’s a good primer to electromagnetic radiation.
g Cosmicus - Over the course of more than 45 years, and through more than 115 books, Ben Bova has been chronicling space exploration as fiction and fact. But in his latest novel, "Mars Life", Bova uses facts about the Red Planet - plus facts about the blue planet we live on - to weave a tale of interplanetary politics as well as scientific discovery. See article.
g Learning - Not only is Wendy Ehnert the 2008 Outstanding Biology Teacher — she’s also modest. See article.
g Aftermath - Often the advanced science and technology of alien civilizations is touted as a benefit of contact with alien civilizations. So what type of physics would an advanced, extraterrestrial civilization likely possess? See what theoretical physicist Michio Kaku thinks that civilization might know.

SETI radio search primer and Solar System Live

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Message -Here’s a quick, easy to understand primer to SETI’s radio searches and the Fermi Paradox.
g Cosmicus - The aim of the spaceflight movement - exploration and colonization of the universe - is so vast and revolutionary that it cannot be achieved by the ordinary operation of day-to-day social forces and institutions. Consequently, we must be prepared to think in imaginative ways if we are to understand how this "giant step" in human history may come about. See article. Note: This article is from 1985.
g Learning -Here’s a neat Web site: Solar System Live. It allows you to observe the locations of planets at various (modern) dates.
g Aftermath - How would humans react the day after ET landed? A nationwide survey by the Roper Organization in 1999 found that the following: “...one out of four Americans think most people would “totally freak out and panic” if such evidence were confirmed. See article.

Grab-bag comet and maybe we’ve already received an alien message

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Abodes - Astronomers have discovered their first grab-bag comet. Radar observations of the small, icy nucleus of a comet known as Tuttle suggest that it consists of two clumps that touch each other, like the two halves of the number eight. See article.
g Message -If we received a message from an extraterrestrial civilization, would we necessarily realize it? SETI has long scanned the skies for evidence of alien transmissions, while others have proposed a hunt for physical artifacts sent by our distant neighbors. But neutrino physicists at the University of Hawaii have proposed yet another possibility: that humans have already received an extraterrestrial communication, and that we might find the message in our existing observations of the stars. See article.
g Cosmicus - Researchers will soon trek to the rocky slopes of Hawaii's Mauna Kea to test a robot designed for lunar prospecting. Scarab will help scientists understand how to extract water, hydrogen and oxygen from the lunar environment to support human missions. See article.
g Learning - Here’s a great NASA Web site for kids: Astro-venture, where children can search for and design their own planet..
g Aftermath - Book alert: You may have to really scour used book stores for this one: 1976’s “ETI: The First Encounter” considers the consequences to man's view of himself and his world of the first proven contact — when it comes — with beings from another planet. Edited by James L. Christian, this book led the way in reflecting on the next stage in man's gradual self-discovery. Click here for the table of contents and ISBN.

How volcanoes helped life get started and Miller-Urey Synthesis sibling studies

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Abodes - A re-examination of samples from a classic 'origin-of-life' experiment indicates that volcanoes may have played an important role in life's beginnings on Earth. The study could also have implications in determining potential habitats for life beyond our planet. See article.
g Life - A classic experiment proving amino acids are created when inorganic molecules are exposed to electricity isn't the whole story, it turns out. The 1953 Miller-Urey Synthesis had two sibling studies, neither of which was published. Vials containing the products from those experiments were recently recovered and reanalyzed using modern technology. See article.
g Message -Could intelligent beings in another solar system have hidden their sun by knocking their planets apart and using the pieces to build a hollow ball around their sun? For more on “Dyson Spheres,” see article.
g Cosmicus -The recent book "Moondust: In Search of the Men Who Fell to Earth" shows how the Apollo program changed the lives of the astronauts who walked on the Moon. This leap to another world also colored our perception of what it means to be stuck on Earth.
g Learning - Discover the universe, its components and origins — play “Spaceball”. Here’s a Web site structured as if a championship baseball game is being played between a celestial object and a spacecraft. Besides being fun, it helps children explore our solar system and the people and spacecraft that made our adventures in and knowledge of space possible.

Searching for cells in Martian minerals and if we did contact another intelligent life form in the universe

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Life - Using a highly sensitive laser, scientists have developed a new method to search for cells in Martian minerals. The technique reduces the risk of contamination and can detect incredibly low concentrations of biomolecules. See article.
g Message - By 2010 we will know if nearby planets are inhabited. That's the amazing claim that Stuart Clark - director of public astronomy education at the University of Hertfordshire - makes in his thought-provoking book, “Life on Other Worlds and How to Find It.” See article. We’re just a couple of years from finding out of his prediction is correct!
g Cosmicus -The company responsible for brokering the first two space tourist missions to the International Space Station announced plans for a mission that will send space tourists to the far side of the moon at the cost of $100 million per person. See article.
g Aftermath - What if we did contact another intelligent life form in the universe? Should we respond? What should we say? What traits best represent our humanity? Douglas Vakoch, the SETI Institute’s director of Interstellar Message Composition, is working with scientists, artists, linguists, composers, and others to imagine how to speak for our planet.

How humans could adapt to the rigors of space and how to help SETI discover life

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Life - Tardigrades, commonly known as "water bears", have been reared under laboratory conditions and subjected to a barrage of tests. Their survivability shows that animals can survive extreme conditions, and also may indicate how humans could adapt to the rigors of space. See article.
g Message -Want to help SETI discover alien life? If you haven’t already done so, download the free SETI at Home software. Using Internet-connected computers, the program downloads and analyzes radio telescope data on your desktop when it is idle. The program has been so successful in plowing through data that other scientific researchers, especially in medicine, are adopting it to their fields. Click here for the program.
g Cosmicus -Proponents of small satellites say that tiny spacecraft have potentially big roles to play in planetary exploration. See article.
g Aftermath - If we find other civilizations, what will we say to them? Crafting a message that represents Earth and humanity and can be understood by another life form is no minor endeavor.

You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Abodes -Venus Express is being used to observe the Earth from its orbit around Venus. Astronomers hope that the data will help develop techniques to search for habitable planets around distant stars. See article.
g Life - Developing strategies for finding life on other planets and in extreme environments on Earth will be the focus of Penn State's new astrobiology initiative under a five-year grant from NASA's Astrobiology Institute for "Signatures of Life from Earth and Beyond." See article.
g Message -It's not easy to look for life somewhere other than Earth. First, scientists searching for life in space have to come up with a working definition of 'extraterrestrial life'. Next, they need to develop a strategy identifying places and methods for their search. To make matters more complicated, all of this has to be done without contaminating the search site with life from Earth or contaminating Earth with potential extraterrestrial life. See article.
g Cosmicus -Kevin Knuth has a laboratory in the physics department of the University at Albany that is filled with LEGOs. The bricks are relatively cheap and can be used to rapidly prototype a robot's body. Knuth's robots are being programmed to solve such problems as mapping complex terrain. See article.
g Learning -Three young researchers are starting exciting new fellowships in UK Universities dedicated to exploring and uncovering the mysteries of our Solar System. See article.
g Imagining -Venus's battery-acid clouds might very well support microbial life - like the "extremophile" microorganisms that Earth scientists have found thriving near volcano outflows. See article. Note: This article is from 2004.

Detecting Mars-sized planets in other solar systems and the raw materials for life among the stars

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Abodes -Astronomers may have discovered a new method for detecting planets as small as Mars orbiting distant stars. The method would open a new avenue in the search for habitable planets in the universe. See article.
g Life - The stuff of burnt toast, auto emissions and life itself has been spotted in galaxies so far away they are seen at a time when our universe was just one-fourth its current age. The discovery of organic molecules, called hydrocarbons, shows that the raw materials for life were present long before our solar system formed. See article. Note: This article is from 2005.
g Cosmicus -Even though political tensions between the United States and Russia remain strained and global economic problems are causing credit crunches, space exploration will take place as scheduled, the head of Russia's space agency said over the weekend. See article.
g Imagining -Science fiction authors produce a lot of very strange critters. In the desperate dash to be different, many go way overboard to invent fantastic, outlandish species unlike anything anyone has ever seen. It’s an admirable expression of their artistic abilities, but there’s an inherent problem: They almost always lose the reader along the way. Sure, it sounds ultra-cool to have a whole herd of 80-foot quasi-limbed orb-stasis beings, but unless you draw me a picture of these things, the reader often has no idea what you’re talking about. However, if you write that your alien has four wings, 10 eyes and looks a little like a kangaroo, the reader is right there with you. Most readers need at least something familiar to draw on for their imagination, or they get lost. See article. Note: This article is from 2002.
g Aftermath - It is sometimes said that the best form of advertising is education. But what products would our global marketplace tolerate at the borders of an encounter with another, perhaps far different civilization? To get some perspective, an expert entertains the question of how to advertise our presence to a more universal demographic. See article. Note: This article came out in 2004.

Telescope tech and SETI history

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Abodes - The hunt for extraterrestrial life is getting a major boost from revolutionary new technology that will give some of the world's largest telescopes the capability to detect Earth-size planets outside of our solar system, a feat not equaled even by the Hubble Space Telescope. See article.
g Life - NASA has picked up a research team from Arizona State University to boost the search for extraterrestrial life, by refining the criteria that guide the search for life. See article.
g Message - Want to get a sense of SETI’s history and varying projects? Jodrell Bank Observatory offers an easy to follow yet informative primer.
g Learning -DVD alert: In 2007 the History Channel launched a new documentary style series that took on a topic with more content than could ever be discussed. The Universe debuted to masses and became an instant success thanks largely in part to its quality production, but mostly due to an audience hungry for more. With shows like Planet Earth being all the rage, History Channel took that idea and expanded upon it, showing us detailed features of planets within our own solar system and even those beyond. The first season was a hit on DVD, and just about a year later it's time to check out the second collection of episodes.
g Imagining -Quantum physics and biochemistry is real, hard as nails science, say many physicists and also, it appears, those who write SF books and screenplays. But, reproductive biologist Jack Cohen asks, “Is biology a science?” And what affect does the answer have on our ability to imagine and recognize extraterrestrial life? See article. Note: This article is from 2002.
g Aftermath - What affect would the discovery of alien life have on the story-telling genre that inspires the search for it — science fiction? See article.

Analyzing Martian soil and if science fiction aliens look too much like humans

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Abodes - NASA's Phoenix Lander is continuing to analyze the soil of Mars, providing further indications that liquid water was present at the surface. This is the first step in determining if Mars was once habitable for life as we know it. See article.
g Learning -Americans love science in their movies and TV shows, yet recent reports indicate we are losing our scientific dominance to the rest of the world. Can science-themed entertainment get Americans off the couch and into the lab? See article. Note: This article is from 2004.
g Imagining - A complaint lodged again and again against science fiction aliens is that they look too much like us. Is that complaint valid? Is it so unlikely that extraterrestrials would look at least similar (though not identical) to humans? If so, then what would beings, intelligent or not so intelligent, who evolved on another world look like? That's what Cliff Pickover explores in The Science of Aliens. Though the book is a few years old, it’s still worth reading.
g Aftermath - Humans live and die by approximations. We are seldom as perfect or as accurate as we would like to be. And as we contemplate what we might say to an advanced extraterrestrial civilization, maybe that's a point we should emphasize. See article. Note: This article is from 2003.

Extinction events and the Golden Record

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Life - Geologists studying mass extinctions in Earth's history have determined that the majority of extinction events were due to climate change rather than asteroid impacts. See article.
g Message -The two Voyager deep-space probes each hold gold-plated copper discs - called the "Golden Record" - to be played on a record player (supplied on board) and containing a snapshot of information from Earth. Assuming the aliens can assemble the player and figure out the instructions, they're in for quite a treat: a deep-space personal ad for the entire human race, assembled under the direction of Carl Sagan. But while the first couple of plaques are neat - they deal with basic number systems and offer cryptic hieroglyphic instructions on how to play the records - the remainder of the album is pretty poor, a Yale graduate student says. Note: This article is from 2004.
g Cosmicus -To inspire the American people about the Vision for Space Exploration, and to focus the agency on its central mission, NASA should immediately establish a Moon and Mars Astronaut Corps. This elite cadre, set up within the existing astronaut body, would bring together the heroes who will lead the great journey ahead. See article. Note: This article is from 2005.
g Imagining -Nobody has yet seen an extraterrestrial, which may sound like a problem in establishing a science of astrobiology. But in the past 20 years or so, scientists have found clues that life may be quite common in the universe, and many are hopeful that they will soon find hard evidence of life beyond Earth. See article.
g Aftermath - Will we ever find a primer for decoding messages from extraterrestrials? Last month, anthropologists who gathered for a major conference in Atlanta heard some news that will be sobering for SETI enthusiasts: it may be much more difficult to understand extraterrestrials than many scientists have thought before. See article. Note: This article is from 2005.

Single species ecosystem and predicting reactions to proof of an otherworldly intelligence

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Life - The first ecosystem ever found having only a single biological species has been discovered 1.74 miles beneath the surface of the earth in the Mponeng gold mine near Johannesburg, South Africa. There the rod-shaped bacterium Desulforudis audaxviator exists in complete isolation, total darkness, a lack of oxygen, and 140 degrees Fahrenheit heat. See article.
g Message -Separating static from signal is a classic problem for SETI researchers. Whether such a viable signal might be more promising if it were broad-spectrum or sharp like a tuning fork, has an influence of how much message it can carry and how far it may travel. See article. Note: This article is from 2003.
g Learning -While we yearn to walk on other worlds, SETI Institute scientist Cynthia Phillips strolls the surfaces of distant planets each day at her computer. She's a planetary geologist on a quest to understand how liquids change the surfaces of other worlds. She studies Mars and the icy moons of the outer solar system, mapping the evolution of their surfaces. It's all part of the search for life beyond our home planet, Earth. See article.
g Imagining -Like first contact stories? Then be sure to read Larry Niven and Jerry Pournelle’s “The Mote in God's Eye” (1974), a classic hard science fiction novel.
g Aftermath - How can we predict reactions to proof of an otherworldly intelligence? Some scientists argue that any unpredictable outcomes can only be judged against our own history. See article..

Earliest animals with legs and designing an interstellar message

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Abodes -Eight years from now, the Juno spacecraft will arrive at Jupiter, with instruments to study its atmosphere. Research goals for the mission include determining how the giant planet formed, how much water it contains, and how its powerful auroras compare to Earth’s Northern Lights. See article.
g Life - The fossilized trail of an aquatic creature suggests that animals walked using legs at least 30 million years earlier than had been thought. Scientists once thought that it was primarily microbes and simple multicellular animals that existed prior to the Cambrian, but studies like this may change that notion. See article.
g Message -To design an interstellar message, does one have to find ways to communicate that humankind has the potential to be friendly, loving and altruistic toward non-kin individuals or strangers? How to announce our stewardship of the planet as a good neighbor? See article. Note: This article is from 2003.
g Learning -A team of scientists gathered at Edinburgh's Royal Observatory last night to pose the question: "Are We Alone in the Universe?" See article.
g Imagining -Like stories about efforts to communicate with alien? Then be sure to read Fred Hoyle’s “A for Andromeda” (1962).

You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Abodes -Cassini will soon fly within 16 miles of Enceladus' surface to measure molecules in the Saturnian moon's environment. The data will provide insight into the early history of the solar system. See article.
g Life - University of Hawaii researchers will expand investigations and education on the origin, history and distribution of water and its relationship to life in the universe under a new multimillion-dollar NASA astrobiology grant. See article.
g Message -Book alert: Scour your used book store shelves for “Life Beyond Earth”, by Timothy Ferris. Rock-solid science writer Ferris has covered this ground before. In the two-hour PBS documentary that he wrote and narrated - which shares the title, text, and many of the images of this generously illustrated book - Ferris tackles two age-old questions about the potentially universal nature of life: Are we alone, and, if not, is anybody listening?
g Learning -The origins of life in our galaxy and the search for alien life outside our solar system will be at the forefront of discussions by experts in Edinburgh. See article.
g Imagining -Like stories about alien anthropology and cultures? Then be sure to read Robert Silverberg’s “Downward to the Earth” (1970), in which a colonial administrator tries to do justice to alien culture.
g Aftermath - What do modern explorations reveal about alien life and the role that humans play in the story of the cosmos? Join internationally recognized planetary scientist David Grinspoon for his lively discussion of recent findings in astrobiology. WBGH recorded the discussion earlier during 2005 in Boston.

Extinction crisis and original sin among aliens

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Stars -Two Japanese scientists and a Tokyo-born American shared the 2008 Nobel Prize for physics for helping to explain the behavior of subatomic particles, work that has helped shape modern physics theory, the prize committee said today. See article.
g Life - An “extinction crisis” is under way, with one in four mammals in danger of disappearing because of habitat loss, hunting and climate change, a leading global conservation body warned on Monday. See article.
g Message - Book alert: In “Is Anyone Out There?”, by Frank Drake, Dava Sobel, University of California astronomy and astrophysics professor Drake, aided by science journalist Sobel, responds to the title's classic question with an account of his career-long quest to gamer hard scientific data that might point to some answers. One of America's pioneer radio astronomers, Drake provides firsthand descriptions of breakthrough moments in the past 30 years of astrophysics - no encounters of any kind, just straightforward astrophysics with inconclusive experimental results. Drake's medium is science, his theory technical and his slightly anthropocentric conclusions more modest than those of the average UFO abductee.
g Imagining -Like stories about alien anthropology and cultures? Then be sure to read James Blish’s classic novel “A Case of Conscience” (1958), in which he explores if original sin exists among the Lithians.
g Aftermath - Here’s a fascinating idea: A group of serious scientists, writers, military leaders and others discussing how to establish a constructive dialogue between humanity and ETI, once contact is made.Messages sent into space directed at extraterrestrials may have been too boring to earn a reply, say two astrophysicists trying to improve on their previous alien chat lines.

Measuring ancient Earth’s air and ‘Are We Alone …?’

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Abodes -In the first study of its kind, researchers will measure the air pressure from nearly three billion years ago by using gas bubbles in lava and tiny craters made by raindrops. The results could indicate what sort of life may have existed on the ancient Earth. See article.
g Life - MicroRNAs are tiny molecules used to fine-tune how genes are expressed. Now scientists are beginning to understand the early evolution of these important molecules and how they have affected the evolution of life on our planet. See article.
g Message -Never before has so much time and concentrated effort been spent by so many scientists and writers in pursuit of the answer to this fundamental question. In “Are We Alone in the Cosmos? The Search for Alien Contact in the New Millennium”, by Byron Preiss and Ben Bova (editors), major scientists involved in the Search for Extraterrestrial Intelligence explain their work and reveal their thoughts. Joining them are some of the best speculative thinkers, from Arthur C. Clarke and Isaac Asimov to Gregory Benford, who address the major philosophical questions involved.
g Cosmicus - Top NASA managers will decide next week the fate of the Mars Science Laboratory, a nuclear-powered astrobiology rover that already has cost $1.5 billion and is likely to hit the 30-percent overrun ceiling that could trigger cancellation by Congress. See article.
g Imagining -Like stories about alien biologies/environments? Be sure then to read Olaf Stapeldon’s classic novel “Star Maker” (1937). See article.
g Aftermath - According to astronomer Allen Tough, even before a signal is detected, six positive consequences will result from the scientific search for extraterrestrial intelligence, usually called SETI. (1) Humanity's self-image. SETI has enlarged our view of ourselves and enhanced our sense of meaning. Increasingly, we feel a kinship with the civilizations whose signals we are trying to detect. (2) A fresh perspective. SETI forces us to think about how extraterrestrials might perceive us. This gives us a fresh perspective on our society's values, priorities, laws, and foibles. (3) Questions. SETI is stimulating thought and discussion about several fundamental questions. (4) Education. Some broad-gauge educational programs have already been centered around SETI. (5) Tangible spin-offs. In addition to providing jobs for some people, SETI provides various spin-offs, such as search methods, computer software, data, and international scientific cooperation. (6) Future scenarios. SETI will increasingly stimulate us to think carefully about possible detection scenarios and their consequences, about our reply, and generally about the role of extraterrestrial communication in our long-term future. Such thinking leads, in turn, to fresh perspectives on the SETI enterprise itself. Read the full paper.

Little bang and Project Argus

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Stars -New research shows that a distant exploding star could have triggered the formation of our solar system. The study is helping astrobiologists understand the conditions in which habitable planets might form. See article.
g Life - The remains of a unique dinosaur discovered in Argentina are helping scientists understand the connections between dinosaurs and birds. The study sheds light on an important moment in the evolution of life on our planet. See article.
g Message -
The SETI League, Inc. launched its Project Argus all-sky survey in April 1996, with the ambitious goal of real-time all-sky coverage. This SETI experiment is unique in that it employs the talents and energies of thousands of dedicated amateur radio astronomers worldwide. In its first four years, Project Argus has grown from five small prototype radio telescopes to more than one hundred operational stations, with hundreds more under construction. The project is still decades away from its projected 5,000 stations able to see in all directions at once. Nevertheless, much has been learned about how to build radio telescopes inexpensively, operate them with the utmost of professionalism, and interpret received data with scientific rigor. See article.

Life on Earth before life as we know it began and deciphering our thought son alien life

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Life - Life may have existed on Earth many times before life on the planet, as we know it, began. See article.
g Message -The Earth is at the center of an expanding bubble of electromagnetic radiation. The bubble, expanding at the speed of light, contains all of the man-made electromagnetic transmissions of the earth - radio, TV, radar, and so on. In theory, an alien civilization could receive these signals, and form their opinion about the earth by analyzing them. To most people, it is quite discouraging to think that some alien civilization would form their opinion of Earth based upon our situation comedies. Upon a slightly deeper analysis, the conventional wisdom says, “Aliens might detect our TV signals, but at least they can't form their opinion of our civilization from our TV transmissions. Decoding the transmission is so much harder than detecting it that we don't need to worry about this.” But an editor of the book “SETI 2020” argues that this view considerably underestimates the technologies that aliens might employ. By looking at likely technical improvements - better receivers and feeds, bigger antenna, signal processing, and perhaps stellar focusing, any civilization that can detect our radiations might well be able to decode it as well. Thus aliens can form their impression of Earth from “I Love Lucy.” See article..
g Imagining -Like stories about communicating with aliens? Then be sure to read Jack Vance’s "The Gift of Gab” (1955), which involves “talking” with intelligent cephalopods.
g Aftermath - Here’s an intriguing article: “How SETI is using the social sciences to decipher our thoughts on alien life”. Note: This article is from 2002.

Microbes from 300 million years ago and NASA awards astrobiology grants

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Abodes - Where should scientists hunt for evidence of Martian life? On Earth, at least, they should scout for white-colored meteorites made of sedimentary rock, a new study suggests. See article.
g Life - Limestone from Namibia has biomarkers that indicate a community of microbes oxidized methane at least 300 million years ago. Such biomarkers can provide clues to the history of life on Earth, and could help scientists search for signs of life on other worlds. See article.
g Intelligence -Quote of the Day: “We are continuing to navigate through the modern world with a Stone Age mind.” – Hank Davis
g Message -The Search for Extraterrestrial Artifacts, or SETA, is about delineating between the artificial and the real. In the case of radio detection from other stellar systems, the artificial is what is labeled the real signal that intelligent communications are on-air. See article. Note: This article is from 2003.
g Learning -NASA has awarded five-year grants, averaging $7 million each, to 10 research teams from across the country to study the origins, evolution, distribution, and future of life in the universe. See article.
g Aftermath - Here’s a neat transcription of a video conference interview with Dr. Frank Drake (whose famous equation this site is organized after), conducted by the class members of Penn State’s "Space Colonization” class. Drake touches on a variety of SETI topics, including the philosophical implication of extraterrestrial contact. Note: The interview took place in January 2001.

Solar system formation and tools to search for extraterrestrial life

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Stars -Now, astrophysicists at the Carnegie Institution's Department of Terrestrial Magnetism have shown for the first time that a supernova could indeed have triggered the Solar System's formation under the more likely conditions of rapid heating and cooling. See article.
g Abodes - New evidence of lake deposits inside Martian impact craters may indicate that precipitation once fed rivers and lakes on Mars. Precipitation at the Martian surface could mean that the planet was once capable of supporting life as we know it. See article.
g Life - Using an artificial meteorite, scientists have determined that organisms in meteorites wouldn't survive a fall to Earth. However, the study does show that meteorites could still retain biosignatures that would provide evidence for life on other worlds. See article.
g Message -Looking for life elsewhere is a tough task for human or robot. The good news is that the scientific skill and tools to search for, detect and inspect extraterrestrial life are advancing rapidly. See article.
g Imagining -Mars was once thought to be the most likely of the planets to harbor life, and so was a great source of inspiration for filmmakers. This review examines Mars in the history of the cinema.
g Aftermath - If some day we detect a radio signal from a distant civilization, we’ll have to make some adjustments in the way we view ourselves. After millennia of knowing of no other intelligence in the universe than humankind, we could face a considerable challenge to our terrestrial egotism. In the process, will we simply gain a little healthy humility about our place in the universe? Or would it be downright humiliating to compare our own meager accomplishments with those of more advanced extraterrestrials? See article. Note: This article is from 2000.

Martian volcanoes and alien technology

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Abodes -Although volcanoes on Mars today are dormant or extinct, in the distant past the Red Planet was literally a hotbed of volcanic activity. Cerro Negro, an active volcano in Nicaragua, offers clues to what the Martian era of fire and brimstone may have been like – and what types of organisms could have lived in that superheated world. See article.
g Message -Tired of the alien-of-the-week as depicted by "Star Trek"? Jar-Jar Binks bugging you? Are you wondering where the real space sentients are, and if they are weirder than we can even imagine? You are not alone – and in all probability, we are not alone either. At least, that’s what the folks at SETI – the Search for Extra- Terrestrial Intelligence – are betting. See article.
g Learning -A new NASA contest challenges college-level students to design tools or instrument packages that could be used on the next generation of human-driven moon rovers. Student will have the opportunity to engage in NASA's return to the moon by designing equipment that will help astronauts accomplish tasks on the lunar surface. See article.
g Imagining -In nearly all popular science fiction dramatizations on television, most of the alien protagonists look remarkably like humans. In "Star Trek," if you forgave the Vulcan's their ears (and their hair-styles), the Klingons their foreheads and the Bajorans their ridged noses you'd think that they were all human. After all, they have two legs, two arms, 10 fingers and toes, two ears, two eyes and a nose. And while arms and eyes are universals, two arms and two legs are parochial. See article.
g Aftermath - Visitors from other worlds – should any appear – would be enormously ahead of us from a technological viewpoint. The same is true for any aliens we might tune in with our SETI experiments. See article. Note: This article is from 2000.
