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 mysterious ribbon spotted on the edge of the solar system has turned out to be a reflection of particles streaming off the sun, scientists have found. See article.
g Abodes - Blobs of warm ice that periodically rise to the surface and churn the icy crust on Saturn's moon Enceladus explain the quirky heat behavior and intriguing surface of the moon's south polar region, according to a new paper using data from NASA's Cassini spacecraft. See article.
g Life - How does life begin and evolve? Is there life elsewhere in the Universe? What is the future of life on Earth and beyond? Today, NASA's Astrobiology Institute (NAI) is not only asking these age-old questions, it is actively seeking answers. See article. Note: This article is from 2004.
g Message - Book alert: In response to Enrico Fermi's famous 1950 question concerning the existence of advanced civilizations elsewhere, physicist Stephen Webb in “If the Universe Is Teeming with Aliens... Where Is Everybody? Fifty Solutions to Fermi's Paradox and the Problem of Extraterrestrial Life” critically examines 50 resolutions to explain the total absence of empirical evidence for probes, starships, and communications from extraterrestrials. He focuses on our Milky Way Galaxy, which to date has yielded no objects or signals that indicate the existence of alien beings with intelligence and technology. His comprehensive analysis covers topics ranging from the Drake equation and Dyson spheres to the panspermia hypothesis and anthropic arguments. Of special interest are the discussions on the DNA molecule, the origin of life on Earth, and the threats to organic evolution on this planet (including mass extinctions). Webb himself concludes that the "great silence" in nature probably results from humankind's being the only civilization now in this galaxy, if not in the entire universe. This richly informative and very engaging book is recommended for most academic and public library science collections. See reviews.
g Cosmicus - The first wealthy tourists rocketing into space from Florida may start their trips in Jacksonville, not the Space Coast. See article.
g Learning - The SETI Institute regularly invites Explorers of the Universe to a weekly lecture held in Mountain View in northern California. Each talk is delivered by leading scientists and engineers in their field of expertise, and each topic is easily introduced for the uninitiated. See article.
g Aftermath - During the last hundred years, Homo sapiens has been flamboyantly belching clues into space that could alert technically savvy extraterrestrials of our presence. Radar and television, odd chemical compounds in the atmosphere, and even the occasional spacecraft sent beyond the heliopause are all messages in bottles that could conceivably wash up on the shores of ET’s planet. So why don’t they come here and kill us? See article. Note: This article is from 2008.
