Yes, I happen to know a little about that. Learned all about spectroscopes when I was a youngsters. I had a feeling you'd go there...
But thanks for the tip...
By the way, did you know they found life, surviving and living just fine a few feet below ground at nuclear test sites?
Life is indeed very tenacious. I would not be surprised to find bacterial life on Mars or one of the near-Earth asteroids.
But the question of where life, and more importantly the information that makes life possible came from is another question entirely. It has not been answered by the old standbys (Miller-Urey experiment), and the origin of life conventions, at least as of a few years ago, had no new theories; indeed, they are all moving toward panspermia, which just moves the question of origins back one planet.
