This report explores the connection between geomicrobiology and astrobiology, explaining NASA's interest in the natural history of Yellowstone National Park. Multi-institution research teams are attempting to use Yellowstone's geothermal systems to understand how life began on Earth and how it could exist on other planetary bodies. Topics include the origin and evolution of life, and the current and future directions in the exploration for life elsewhere in the universe.
