The search for extraterrestrial life is on! Whether on the dry, dusty surface of Mars or below Europa's ice surface, astrobiologists are looking for signs of life. But before a spacecraft or robotic mission is launched, how do scientists know where to look? As it turns out, many clues can be found right here on Earth. Understanding what is needed to sustain life, and where habitable environments might be found, is fundamental to the search. The study of microscopic organisms collectively known as extremophiles has dramatically altered how and where researchers look for life. If these hardy creatures can thrive in the darkest depths of the ocean, in hot sulfuric pools and geysers, and in harsh arid regions here, then perhaps life can be found on other worlds in similar environs.
