Astrobiology is the study of the origin, evolution, distribution, and future of life in the universe. Astrobiologists address three fundamental questions: How does life begin and evolve? Is there life elsewhere in the universe? What is the future of life on Earth and beyond?
Icy moons in our solar system are some of the places astrobiologists are studying to search for signs of life beyond Earth.
Astrobiology at water-rock interfaces found on icy bodies such as Europa and Enceladus, is the unifying theme of the JPL Icy Worlds team. Several of the icy moons in our Solar System have subsurface oceans that, combined, contain many times the volume of liquid water on Earth.
