Scientists found first sign of a source for extraterrestrial microbial life. NASA’s Cassini spacecraft is all set for its final activity at Saturn. Hydrogen has been detected in an ice piece of Saturn’s ocean bearing moon. When hot water interacts with rocks creating an active space for microbial life which is not dependent on photosynthesis for survival is known as Enceladus.
On Earth such microbes are found near hydrothermal vents on sea. Scientists are thinking that the same process might be true for Saturn’s ice – capped inner moon. The moon is 500 miles in diameter. Scientists said that there might be two possibilities for excess of Hydrogen. One is that there are no microbes to consume Hydrogen and the other is Hydrogen is there, a lot of food for them is also there but there is some limiting factor for their growth. Scientists are not making any claims upon inhabitation on Enceladus.
