NASA has a big press conference planned for Thursday, and it's centered around "astrobiology." Have they discovered extraterrestrial life?
Jason Kottke did some sleuthing into all of the people involved in the press conference and all evidence points to some interesting stuff about Saturn's moon Titan. People involved include a geobiologist, an oceanographer, a biologist and an ecologist. There's been a lot of talk about photosynthesis using arsenic, and if arsenic has been discovered on Titan that could mean life. Exciting stuff! We'll know more on Thursday.
Update: Looks like Kottke has published an update from The Atlantic senior editor Alexis Madrigal, who claims to have read NASA's upcoming brief. The verdict? No little green men yet.
