Life On Mars: ALH84001

Celestius writes "This press release from NASA Ames states that 'An international team of researchers has discovered compelling evidence that the magnetite crystals in the martian meteorite ALH84001 are of biological origin,' and moreover that these crystals are not only older than any previously known form of life, but were also definitely formed before the meteor fell to Earth. Skeptics remain, of course, as quoted in this article from today's Chronicle, but suffice to say, NASA seems pretty confident." There's also a report on the BBC as well.
