A five-part series on the ultimate limit on technology, and how that limit could help us find other civilizations: 1 2 3 4 5 [via]
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

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.
is an astrophysicist, Director of the Origins of Life Initiative
at Harvard and a co-investigator of the Kepler space telescope project
to find Earth-like planets
around the Cygnus constellation
and discover extraterrestrial life. But no matter how successful the Kepler project may be, it still won't answer the most fundamental questions of astrobiology: How diverse is life in the universe? If alien life exists, will it have Earthly DNA and proteins? Or will it run on something else? So Dr. Sasselov has decided to collaborate with two synthetic biologists, asking them to create a life form based on mirror-image versions of what we know as the essential building blocks of living things on Earth.

Is life possible even in the coldest depths of space?
If so, this tough little guy
has long been thought to be a good candidate. Now, finally, analysis of the Tardigrades
(a.k.a. "water bears") exposed to open space as part of the TARDIS project
is finally complete. So what's the verdict? [more inside]
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
Real robot drama is happening on Mars today. Spirit
, racing for her life
to find shelter before winter, injured
after four years of hard labor, may have made her most significant find yet. The broken foot she's dragged behind her for the past two years unexpectedly uncovered evidence of a once-wet Mars with conditions theoretically hospitable for primitive life
: ESA telescope detects planet
20 lightyears away with a temperature between 0 and 40 degrees Celsius, dubbed "most Earth-like planet yet
ESA scientists announced that a giant sea is hidden under the Martian surface.
With discoveries like this
and weird photos like this
, how long can it be before we find conclusive proof of extraterrestrial life?
- a strong case for life on mars was presented sunday
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)
First Evidence of life coming from space.
One third a ton a day raining down, according to these researchers.
