Life on Saturns Moon Enceladus?? NASA Explains How This Could Be Possible









NASA hailed a ‘new frontier’ last night after revealing some of the strongest evidence yet that alien
life may exist.

The space agency said that practically all the elements needed for life had been discovered in the same place in our solar system – on one of Saturn’s icy moons.

The missing ingredient, hydrogen, was discovered for the first time on Enceladus during the deepest ever dive by NASA’s Cassini spacecraft.

This hydrogen is now said to be ‘a potential source of chemical energy that could support microbes on the seafloor of Enceladus,’ the researchers revealed during a NASA press conference yesterday.



Enceladus was discovered by William Herschel on August 28, 1789, during the first use of his new 1.2 m (47 in) telescope, then the largest in the world.[15][26] Its faint apparent magnitude (HV = +11.7) and its proximity to the much brighter Saturn and Saturn's rings make Enceladus difficult to observe from Earth with smaller telescopes. Like many satellites of Saturn discovered prior to the Space Age, Enceladus was first observed during a Saturnian equinox, when Earth is within the ring plane. At such times, the reduction in glare from the rings makes the moons easier to observe.[2] Prior to the Voyager missions the view of Enceladus improved little from the dot first observed by Herschel. Only its orbital characteristics were known, with estimations of its massdensity and albedo.

Naming[edit]

Enceladus is named after the giant Enceladus of Greek mythology.[1] The name, like the names of each of the first seven satellites of Saturn to be discovered, was suggested by William Herschel's son John Herschel in his 1847 publication Results of Astronomical Observations made at the Cape of Good Hope.[27] He chose these names because Saturn, known in Greek mythology as Cronus, was the leader of the Titans.
Features on Enceladus are named by the International Astronomical Union (IAU) after characters and places from Burton's translation of The Book of One Thousand and One Nights.[28] Impact craters are named after characters, whereas other feature types, such as fossae (long, narrow depressions), dorsa (ridges), planitia (plains), and sulci (long parallel grooves), are named after places. The IAU has officially named 85 features on Enceladus, most recently Samaria Rupes, formerly called Samaria Fossa.[29][30]
