New Evidence For Ancient Life On Mars
siddesu writes in with "compelling" new data that chemical and fossil evidence of ancient microbial life on Mars was carried to Earth in a Martian meteorite. The finding is being highlighted by the same NASA team who made the initial discovery 13 years ago. Spaceflight Now has more details of the analysis.
Gas bubbles found in the meteorite have a composition that is very much like the atmosphere on Mars. The gas inclusions don't resemble those of Earth.
