Latest evidence shows compelling case for life on Mars

Right when Pound360 was starting to lose hope (and interest) in whether or not there's life on Mars, researchers have detected methane gas on mars using earth-based telescopes. This is particularly fascinating because here on earth, 90 percent of methane is the result of biochemical activity, according to Scientific American's write-up on this story. The remainder is created by "geochemical processes." So, as Scientific American puts it, "Mars is alive! (geologically, biologically or both)."

NASA astrobiologist David McKay
told the Houston Chronicle, "I think this is extremely strong evidence for current life on Mars." Not "pretty good" or "strong" evidence, but "extremely strong."

About Me

I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
