Dwarf planet covered in water ice and aiming radio telescope at Kepler’s found planets
Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:g Stars - How does the G-type star Gliese 314 A compare to our own sun? See article.
g Abodes - A new study shows that the dwarf planet Haumea and one of its satellites are covered in water-ice due to tidal forces between them and the heat of radiogenic elements. See article.
g Life - A new study is helping scientists understand how certain yeasts developed their ability to ferment sugar. This process of ethanol production is a key step in making products like wine. The work is providing new information about the mechanisms that link evolution and environment. See article.
g Message - So far, NASA's Kepler space telescope has identified 1,235 possible extrasolar planets. Now, astronomers are aiming a radio telescope at the most Earth-like ones to see if they can detect advanced civilizations that might call these planets home. See article.
g Cosmicus - r the first time, scientists have demonstrated a version of the Doppler effect at an extremely small level - the rotation of an individual molecule. Rotational Doppler effect is used to determine the rotational velocity of planets and could now help study the properties of molecules. See article.

How hot Jupiters flipped their orbits and exploring Canadian lakes to prepare for Mars
Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Stars - What is the potential habitability of Kapteyn’s Star, a M-type star less than 13 light years from Earth? See article.
g Abodes - A rare number of hot Jupiter planets orbit their stars in a direction opposite to the star's rotation. This violates basic ideas of planet and star formation. Now, new research may explain how these planets flipped their orbits. 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. This article is from 2002.
g Cosmicus - How can the exploration of a Canadian lake, using deep-water submersibles, help NASA plan for the human exploration of Mars? See article.

New ways of finding rogue worlds and visualizing microbial interactions
Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - Some planets that roam the galaxy without a star to call home still may be able to host life. Finding such rogue planets is difficult, but new research suggests these wandering worlds could be detected by their atmospheric auroras. See article.
g Life - Scientists have developed a new method to visualize microbial interactions. The research could have numerous implications in studying microbial life on Earth and beyond. See article.
g Aftermath - Could humanity ever relate to an alien species? Consider the questioning context of these online speculations about why "Star Trek is human centered?" The latter is an interesting question, possibly creating a situation dealing with a prejudice on the behalf of the writers and producers. However, would a series completely dedicated to another species, such as the Romulans, be successful in a television market? Is it possible that the reasons it wouldn’t be might indicate humanity may care little about an alien species other than as a potential threat? See article.

Methane sources on Mars and creating a believable alien species
Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - New images of the Nili Fossae region are helping scientists understand unique geological features in the area. Methane in Mars' atmosphere is enhanced over Nili Fossae, leading some scientists to believe that the gas is produced there. The origins of the Mars methane could be geological or perhaps even biological. See article.
g Life - A new book outlines the history, origin and evolution of the nematode, or roundworm. Nematodes have been around for at least 400 million years, play a key role in soil biology and help support much of the planet and animal life on Earth. See article.
g Imagining - No longer can a science fiction writer create a goo-dripping alien just because a story line requires an adversary from another planet to drop in on our unsuspecting world. The average reader is not going to buy into the B-rated movies of old; it takes more than an actor in a rubber mask for them to suspend their disbelief and enjoy a story or novel. Bringing an alien species into a novel requires a bit of planning and thought on the part of the writer. See column.

Nanoparticle food sources and potential habitability of Teegarden’s Star
Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Stars - What is the potential habitability of Teegarden’s Star, an M-type star a little more than 12 light years from Earth? See article.
g Life - New research has helped locate the source of iron that bacteria and tiny plants on the ocean floor use to survive. Deep sea hydrothermal vents release pyrite nanoparticles that are so small they become dispersed in the ocean to form a potential food source for life in the deep sea. See article.
g Message - When the Voyager 1 and 2 spacecraft were launched in 1977, they each included a gold-plated phonograph record (a "golden record") of natural sounds, greetings in human voices, and a variety of music. The record cover has symbolic instructions that show how to use and understand the record, though scientists still debate whether other civilizations will be able to decipher them. For info on Voyager’s golden record, see article.

One of the earliest minerals formed in solar system discovered and calculating the Hoyle state
Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Stars - After decades without success, scientists have now calculated the Hoyle state. The Hoyle state is an energy-rich form of the carbon nucleus and is the key to understanding the fusion reaction that leads from helium gas to carbon. Without this type of carbon nucleus, life might not exist. See article.
g Abodes - Scientists have discovered a new mineral, krotite, which is one of the earliest minerals formed in our solar system. The finding could help astrobiologists understand how the Solar System formed and evolved, leading to conditions for a habitable Earth. See article.
g Cosmicus - India is moving towards formally joining a me¬ga global initiative aimed at co¬nstructing the world’s lar¬ge¬st and most sensitive radio telescope that will help expl¬ore unknown territories in science. See article.

Calculating the Hoyle state and 2016 astrobiology mission options
Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - El Niño and its partner La Niña, the warm and cold phases in the eastern half of the tropical Pacific, play havoc with climate worldwide. Predicting El Niño events more than several months ahead is now routine, but predicting how it will change in a warming world has been hampered by the short instrumental record. An international team of climate scientists has now shown that annually resolved tree-ring records from North America, particularly from the Southwest, give a continuous representation of the intensity of El Niño events over the past 1100 years and can be used to improve El Niño prediction in climate models. See article.

g Intelligence - Computer networks that can't forget fast enough can show symptoms of a kind of virtual schizophrenia, giving researchers further clues to the inner workings of schizophrenic brains, researchers at The University of Texas at Austin and Yale University have found. See article.
g Cosmicus - Three science investigations of interest to astrobiology are being considered for a 2016 NASA mission: to look at Mars' interior; study an extraterrestrial sea on Titan; or study a comet's nucleus in detail. See article.

Mars’ deep fractures and tourist trips around the Moon
Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - Newly released images from the European Space Agency's Mars Express show Nili Fossae, a system of deep fractures around the giant Isidis impact basin. Some of these incisions into the Martian crust are up to 500 m deep and probably formed at the same time as the basin. See article.
g Life - In 250 million years of insect evolution, the appearance of new wings is unprecedented. Transformations and losses of wings, yes, but additions, never. A team has shattered this belief by providing proof that the exuberant helmet of Membracidae, a group of insects related to cicadas, is in fact a third pair of profoundly modified wings. See article.
g Intelligence - Sleeping worms have much to teach people, a notion famously applied by the children's show "Sesame Street," in which Oscar the Grouch often reads bedtime stories to his pet worm Slimy. Based on research with their own worms, a team of neurobiologists at Brown University and several other institutions has now found that "Notch," a fundamental signaling pathway found in all animals, is directly involved in sleep in the nematode C. elegans. See article.
g Message - From the archives: Should we modify the Drake Equation to account for civilizations which actually engage in deliberate interstellar transmission? See article.
g Cosmicus - Fifty years after the first American astronaut rocketed into space, one commercial spaceflight company is hoping to push the envelope even further, with tourist trips around the moon. And now they plan to use a bigger spaceship. See article.
g Learning - The second issue of the Astrobiology Graphic Novel is now available! Download the pdf or the mobile app! Issue #2 maintains the look and feel of the first issue, but this time the novel chronicles the history of our exploration of Mars. See article.

Solar system’s oldest minerals and microbes on the Moon
Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - In the May-June issue of the journal American Mineralogist, a team of scientists announced the discovery of the new mineral krotite, one of the earliest minerals formed in our solar system. It is the main component of an unusual inclusion embedded in a meteorite (NWA 1934), found in northwest Africa. These objects, known as refractory inclusions, are thought to be the first planetary materials formed in our solar system, dating back to before the formation of Earth and the other planets. See article.
g Life - New research is helping astrobiologists understand the end-Permian extinction, a dramatic biological crisis that profoundly affected the history of life on Earth. However, the new data indicates that this major extinction event may not have been catastrophic for some organisms. See article.
g Message - Recent discussions within the SETI community have thoroughly explored the issue of whether people with access to radio telescopes should send powerful signals to alien civilizations without some process of prior international consultation. In particular, those exchanges have focused on the question of "Active SETI." See article.
g Cosmicus - There has been a long-lived bit of Apollo Moon landing folklore that now appears to be a dead-end affair: microbes on the Moon. See article.

Titan’s underground ocean and what we’ll learn about ourselves by finding ETI
Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - Oddities in the rotation of Saturn's largest moon Titan might add to growing evidence that it harbors an underground ocean, researchers suggest. See article.
g Life - Over 100 million years ago, the understory of forests was dominated by plants from the class Equisetopsida. Now, only one genus from this once-diverse group survives. Now, scientists believe that the horsetail may be the oldest genus of land plant on Earth today. See article.
g Intelligence - Computer networks that can't forget fast enough can show symptoms of a kind of virtual schizophrenia, giving researchers further clues to the inner workings of schizophrenic brains, researchers have found. See article.
g Message - What are the chances that an alien signal has been sent our way just at the right moment to splash upon our antennas during that brief interval? If the extraterrestrials beam their broadcasts to the whole galaxy (or at least a big chunk of it), the chances are 100 percent. See article. This article is from 2007.
g Cosmicus - China's state-run news outlets report that preparations of the country's first space station module, called Tiangong-1, are in full swing for a launch in the second half of this year and will be followed by an unpiloted spacecraft. See article.
g Aftermath - Are we alone? Aliens on Earth from the Epicurean Greek philosophers more than 2000 years ago to fiction writers of the late 19th century, people have speculated about the possibility that there might be other worlds which are home to alien life. Yet it is only with the gigantic telescopes and interplanetary probes of the space age that we finally have a realistic hope of answering the question. As we learn more about our own planet and the evolutionary history of terrestrial life we feel a stronger urge than ever to put it into context. Embarking on the search for extraterrestrial life pushes our technology and scientific understanding to the limits, but the quest is one we should not shirk. Finding life beyond our own planet would teach us things about ourselves we might never otherwise learn. See article.

How much SETI really costs and space-time vortex around Earth proven
Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - On Nov. 8, 2011, the asteroid 2005 YU55 will be making a relatively close flyby of Earth. There is no threat of a collision between the asteroid and our planet, but its approach will provide scientists with a close-up view of a 400-meter-wide space rock. See article.
g Life - The cactus is teaching scientists about the evolution of plant communities all over the world. See article.
g Message - SETI, the international organization which handles the search for electromagnetic transmissions from civilizations on distant planets, will shut down soon due to lack of funding. Sure, more pragmatic objectives have to be taken into consideration when budgeting, but heck a measly $2.5 million? If you’re not really sure what $2.5 million really means for SETI, then here’s a really well put together infographic by microcosmologist, which puts into perspective the sum across other sectors of the U.S. budget and other corporations. See article.
g Cosmicus - Results of the NASA's Gravity Probe B indicate that there is a space-time vortex around Earth and that its shape precisely matches the predictions of Einstein's theory of gravity. See article.
g Learning - Two summer graduate courses from Montana State University will help teachers learn about the organisms and ecology of Yellowstone National Park's extreme environments, including the Park's connection to current research in astrobiology. See article.
g Aftermath - Within the scientific community, the question is no longer whether extraterrestrial life exists, but if ET is smart enough to do long division — and the United States and other world governments already have detailed secret plans for first contact. My apologies in advanced for Popular Mechanic’s lurid title, but the reporting is sound. See article. This article is from 2004.

Mourning SETI’s shut down and commercial spaceflight craft passes key test
Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Stars - A spiral galaxy with a dramatic lopsided shape is featured in contrasting views from two telescopes. See article.
g Abodes - Pumice, the rock used remove dry skin from feet, could have been responsible for the birth of life on Earth, scientists have claimed. See article.
g Life - Rice originated in China, a team of genome researchers has concluded in a study tracing back thousands of years of evolutionary history through large-scale gene re-sequencing. Their findings, which appear in the latest issue of the Proceedings of the National Academy of Sciences (PNAS), indicate that domesticated rice may have first appeared as far back as approximately 9,000 years ago in the Yangtze Valley of China. Previous research suggested domesticated rice may have two points of origin -- India as well as China. See article.
g Message - I understand priorities must be set and all spending must be looked at with a critical eye. Still, it is a bit sad that the giant array of radio telescopes in California that are used to search for extraterrestrial life have been closed due to lack of funding. It’s like we’re saying, “ET, we’ve been disconnected. Don’t bother to phone.” See article.
g Cosmicus - A private spaceship built to carry space tourists on suborbital flights for the company Virgin Galactic passed a major glide test flight while flying over California's Mojave Desert on May 4: The spacecraft tested out the novel system it will use when re-entering Earth's atmosphere. See article.
g Learning - 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. See the table of contents and ISBN number.
g Aftermath - As SETI's scientists plan for their first contact with other worlds, who better to consult with than anthropologists, who specialize in encounters with exotic cultures? And thus, over the past several years the SETI Institute has repeatedly brought together anthropologists and scholars from other disciplines, in an attempt to bridge the gap between humans and extraterrestrials. See article.

Still, it is a bit sad that the giant array of radio telescopes in California that are used to search for extraterrestrial life have been closed due to lack of funding. It’s like we’re saying, “ET, we’ve been disconnected. Don’t bother to phone.” See article.
g Cosmicus - A private spaceship built to carry space tourists on suborbital flights for the company Virgin Galactic passed a major glide test flight while flying over California's Mojave Desert on May 4: The spacecraft tested out the novel system it will use when re-entering Earth's atmosphere. See article.
g Learning - 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. See the table of contents and ISBN number.
g Aftermath - As SETI's scientists plan for their first contact with other worlds, who better to consult with than anthropologists, who specialize in encounters with exotic cultures? And thus, over the past several years the SETI Institute has repeatedly brought together anthropologists and scholars from other disciplines, in an attempt to bridge the gap between humans and extraterrestrials.

Looking for aliens in all the exotic places and convergent evolution in lichens
Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - A phenomenon known as “magnetic reconnection” is responsible for much of the space weather that affects Earth. NASA is now preparing a new mission dedicated to studying this dynamic magnetic system and its influence on our planet. See article.
g Life - New research has outlined a case of convergent evolution in two lichen species from separate continents. The study is helping scientists understand mechanisms behind the evolution of life. See article.
g Intelligence - The human eye long ago solved a problem common to both digital and film cameras: how to get good contrast in an image while also capturing faint detail. See article.
g Message - The sad shut down of SETI due to lack of funding brings a major halt to the search for aliens, unplugging the voice and ears which have been doing the search until now. But perhaps we should start thinking outside the box, and start looking for aliens in more exotic places. See article.
g Learning - NASA has made available for the public a new online collection of images of our solar system and locations on Earth where astrobiology researchers travel to conduct field research.

Finding Mars in Morocco and what aliens would find of they ran into the Voyager probes
Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Abodes - From the deepest past to the present day, the deserts of Morocco provide a panorama of life’s history on Earth and give us insight for our investigations of Mars. See article.
g Life - Box jellyfish may seem like rather simple creatures, but in fact their visual system is anything but. They've got no fewer than 24 eyes of four different kinds. Now, researchers reporting online on April 28 in Current Biology, have evidence revealing that four of those eyes always peer up out of the water, regardless of the way the rest of the animal is oriented. What's more, it appears that those eyes allow the jellies to navigate their way around the mangrove swamps in which they live. See article.
g Intelligence - It's one thing to recognize your childhood home when you see it in a photograph and quite another to accurately describe or draw a picture of it based on your recollection of how it looked. A new report published online in Current Biology, offers some of the first clear evidence that monkeys, like humans, have the capacity for both forms of memory. See article.
g Message - The chances of aliens finding Voyager 1 and 2 in the emptiness of space are small. If they do, the two spacecraft could speak volumes about their planet of origin - Earth. See article.

Voyager probes set to leave solar system and Star Trek’s Kaylar
Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Stars - Astronomers from Wales and the Netherlands, in collaboration with five schools, have used eight telescopes simultaneously to study the strange behaviour of an X-ray binary star system. See article.
g Life - Two groups of small fish, one from a Caribbean island and one from the Yucatan peninsula of Mexico, exhibit some of the fastest rates of evolution known in any organism, according to a new study. See article.
g Intelligence - Changes in brain anatomy and the resulting ability to fully exploit electric signal space did indeed lead to rapid speciation, according to a new study. See article.
g Message - The search for extraterrestrial life need not be limited to the government or scientists. Don’t believe it? Then check out this Web site, “Amateur SETI: Project BAMBI (Bob and Mike’s Big Investment),” which describes the design and construction of a 4 GHz amateur radio telescope dedicated to SETI. See article.
g Cosmicus - NASA's twin Voyager 1 and 2 spacecraft are the longest continuously-operating spacecraft in deep space. They have provided invaluable information about the nature of our solar system and the planets it contains. See article.
g Imagining - Could the Kaylar, a Star Trek alien from “The Original Series’ pilot episode, “The Cage,” exist? Like the Gorn, this alien appears to be drawn from our nightmares and hence serves a more dramatic effect than offering any speculation on exobiology. A tall humanoid with intriguing jaw features, skinny legs and broad shoulders, the Kaylar on Rigel VII is reminiscent of a barbarian warrior or an ogre. Brushing aside the nearly impossible parallel evolution between Earth and the Kaylar’s home world for such a creature to come about, there are a couple of possible ways that it could have gained its great height and skinny legs. Its planet might have lighter gravity, which means an indigent alien wouldn’t fall as hard as we do on Earth; hence the supporting legs would not need to be as strong to hold up a little more weight than the typical human. In addition, we might speculate that as a humanoid, the Kaylar shared a similar primate evolution as humans, so possibly the savannah grass of its continental cradle simply was taller than on the African plain during the past few million years; that would have given taller proto-Kaylar an evolutionary advantage. Still, the Kaylar appears to be an unlikely alien.
g Aftermath - From the archives: There’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. The interview took place in 2001.

Earth-sized planet dense as lead and the search for ETI down under
Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Stars - Were spinstars the universe's first polluters? The imprints of fast rotating massive stars have been found in the Milky Way's bulge. See article.
g Abodes - New observations of '55 Cancri e' indicate that the planet is 60 percent larger in diameter than Earth, but eight times more massive. The data also indicates that 55 Cancri e orbits so close to its star that it is baked to a temperature of 4,900 degrees F. See article.
g Life - Amphibian declines around the world have forced many species to the brink of extinction, are much more complex than realized and have multiple causes that are still not fully understood, researchers conclude in a new report. See article.
g Intelligence - Could veterans of war, rape victims and other people who have seen horrific crimes someday have the traumatic memories that haunt them weakened in their brains? In a new study, UCLA life scientists report a discovery that may make the reduction of such memories a reality. See article.
g Message - What are our friends south of the equator doing in the search for extraterrestrial intelligence? After all, the Northern Hemisphere only covers half of the galaxy. See article.
