Maybe FBI Agent Mulder should have spent more time in microbiology class rather than looking to skies to search for alien life. Extremophile organisms are those that thrive in the coldest, hottest, deepest, saltiest, most acidic parts of the habitable earth. They have been studied by scientists as one of the earliest forms of life on Earth, and are capable of everything from running your digestive system to growing gold in soil.
