NASA reveals discoveries on 'ocean worlds' in our solar system!
But just before the grand finale, scientists working on the mission have released the news that form of chemical energy that can support life is available on one of saturn's moons - Enceladus.
The U.S. space agency NASA has identified a moon orbiting Saturn as a new candidate for potential life.

The energy can be obtained from the combination of hydrogen and carbon dioxide dissolved in water.
This graphic illustrates how Cassini scientists think water interacts with rock at the bottom of the ocean of Saturn's icy moon Enceladus, producing hydrogen gas. We know Europa and the moons around Jupiter existed 4 billion years ago so that is a lot more time for life to have emerged and start taking advantage of these energy sources.
On Earth, where we find water, we find life, so that's where we like to look for life in space, too. It is believed the hydrogen came from a hydrothermal reaction between the moon's ocean and its rocky core. "These results demonstrate the interconnected nature of NASA's science missions that are getting us closer to answering whether we are indeed alone or not".
WASHINGTON-NASA has announced that there may be proof of life outside of earth.
From these current observations researchers have determined that almost 98 percent of the gas in the plume is water, about 1 percent is hydrogen and the rest is a mixture of other molecules including carbon dioxide, methane and ammonia.
The research is published a paper in the journal Science and it is noted that hydrogen gas is a potential "chemical energy source for life" and has been found present in the plumes.
"Now, Enceladus is high on the list in the solar system for showing habitable conditions", said Hunter Waite, one of the study s leading researchers.
Not only that, but the plumes on Enceladus are associated with hotter regions on the moon.
"If correct, this observation has fundamental implications for the possibility of life on Enceladus", Seewald wrote.
"This finding does not mean that life exists there, but it makes life more plausible and potentially quite abundant if a fraction of the hydrogen is used to drive biology", Jeffrey Kargel, a professor at the University of Arizona, told The Guardian.
NASA says the discovery will help it to better equip the Europa Clipper mission set for the 2020's when a probe will visit the moon to examine the plumes.
