Hints of Life Found on Saturn Moon
A possible chemical mystery has been found on the Saturn moon, Titan. Funny thing is, the mystery was predicted in 2005 by Chris McKay of NASA's Ames Research Center in Moffett Field and Heather R Smith of the International Space University in Strasbourg, France.
Why did they predict it? It would be a sign of life on the moon. The chemistry suggests that a viable metabolism on Titan could produce a lack of acetylene and hydrogen, and that's what they found.
