In 2005, the Discovery Channel aired Alien Worlds
, a fictional documentary based on Wayne Douglas Barlowe's graphic novel, Expedition: Being an Account in Words and Artwork of the 2358 A.D. Voyage to Darwin IV
." Depicting mankind's first robotic mission to an extrasolar planet that could support life, the show drew from NASA's Origins Program
, the NASA/JPL PlanetQuest Mission
, and ESA's Darwin Project
. It was primarily presented through CGI, but included interviews from a variety of NASA scientists and other experts, including Stephen Hawking, Michio Kaku, John Craig Venter and Jack Horner. Oh, and George Lucas, too. Official site
. Previously on MeFi. [more inside]

Martian Life's Last Stand in the Trenches?
"Scientists have found water-bearing deposits on Mars that are out of step with what was happening elsewhere on the planet, raising the prospect that the sites could have hosted Martian life's last stand."

Dr. Hoover has discovered evidence
of microfossils similar to Cyanobacteria in freshly fractured slices of the interior surfaces of the Alais, Ivuna, and Orgueil CI1 carbonaceous meteorites. The scientist's conclusion is that the fossilized bacteria are not Earthly contaminants but are the fossilized remains of living organisms which lived in the parent bodies of these meteors, e.g. comets, moons, and other astral bodies. The implications are that life is everywhere, and that life on Earth may have come from other planets.

Are plasma crystals alive? Cosmic dust can, in the presence of plasma, creates formations known as plasma crystals. An international team of researchers published a study in the Aug.14, 2007, issue of the New Journal of Physics (PDF here, abstract here) that indicates that these crystals may be more sophisticated than anyone realized. In simulations involving cosmic dust, the researchers witnessed the formation of plasma crystals displaying some of the elementary characteristics of life -- DNA-like structure, autonomous behavior, reproduction and evolution.

The "Great Filter
" is a hypothetical barrier to explain why civilisations are so unlikely to progress to the point of inter-stellar colonisation that we have not encountered any in 40 years of looking. Maybe humanity has already negotiated the filter - as some massive evolutionary improbability - or perhaps it lies in our future as an almost-certain threat to our existence? We should hold our breath as we look for evidence of life on Mars

Germs from Jupiter? Viruses from Venus?
Nope, just live
space-borne bacteria discovered floating around Earth. "Although the bugs from space are similar to bacteria on Earth, the scientists said the living cells found in samples of air from the edge of the planet's atmosphere are too far away to have come from Earth." (via waldo.net)
