Alien Safari, Part I: Slime Worlds
At the most recent NASA Astrobiology Science Conference, a panel of scientists discussed different types of planets where we might find alien life. The meeting began with talks by Seth Shostak, who reviewed the search for extrasolar planets, and Tori Hoehler, who described a place of “colorful microbial goo” called Slime World.
