An ongoing research and exploration by NASA's Cassini spacecraft has so far provided insight into Saturn and its moons. But the recent information sent by the craft is so the first ever promising information which is giving evidence about the hydro-thermal activity on Saturn's moon Enceladus.

The question that whether life is possible on Enceladus has been around ever since the discovery of the signs of a vast ocean beneath the surface of the moon. The latest evidence of the hydrothermal activity resembles the observations made in deep oceans on Earth.

According to the space community, such a discovery on another world opens doors to a plethora of possibilities. They call it a great victory for Cassini, which has spent most of its resources trying to unfold the mysteries of Enceladus.

After going through the readings sent by the craft, scientists concluded that under the icy crust of Enceladus, there is an ocean that covers it entirely. They said that it is now very important to know that the moon is geologically active.

The subsurface ocean and all the geological activity on Enceladus favor the possibility of life. Astronaut John Grunsfeld said, "The locations in our solar system where extreme environments occur in which life might exist may bring us closer to answering the question: are we alone in the Universe".

A research paper published online this week in the journal Icarus stated that the magnitude of Enceladus' slight wobble during its orbit around Saturn. The lead author of the study paper, Luciano Less, said the main implication is that there are potentially habitable environments in the solar system in places which are completely unexpected.

Cassini was launched in 1997 and has been in Saturn's orbit since past 11 years.
