That astonishingly awesome claim comes from Dr. Richard B. Hoover, an astrobiologist at NASA’s Marshall Space Flight Center, who says he has found conclusive evidence of alien life — fossils of bacteria found in an extremely rare class of meteorite called CI1 carbonaceous chondrites. (There are only nine such meteorites on planet Earth.) Hoover’s findings were published late Friday night in the Journal of Cosmology, a peer-reviewed scientific journal.

In order to satisfy the inevitable hoard of buzz-killing skeptics, Hoover’s study and evidence were made available to his peers in the scientific community in advance of the study’s publications, giving them a chance to thoroughly dissect his findings. Comments from those who decided to sift through the evidence will be published online, alongside the study.
