NASA Discovers Why Saturn's Moon Enceladus May Be the Best Place to Look for Alien Life
The scientists of NASA announced its Cassini spacecraft found evidence that the ocean on Enceladus, one of Saturn’s 62 moons, may contain all the ingredients necessary for the emergence of life.
- Cassini flew through plumes of gas bursting out from under the ice covering the oceans and detected a clear presence of molecular hydrogen.
- Findings were made by NASA with the help of Cassini-Huygens unmanned spacecraft and the Hubble Telescope.
- The ingredients of life are liquid water, a source of energy for metabolism, and chemicals such as carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulphur.
- Saturn’s moon Enceladus has a higher possibility of hosting life than Jupiter’s Europa as it has a form of chemical energy on which life forms can feed.
- Enceladus is a small, icy moon which has an abundance of hydrogen molecules in water plumes.
- Scientists expect to find the potential for life in those vents as microbes flourish on Earth in hot cracks on the ocean floors, where sunlight cannot penetrate.
- Underwater vents present on Enceladus resemble the vents present on Earth’s ocean floors, where microbes and other sea life congregate.
