This plume is correlated with a thermal spot of interest, and if the two are connected, says NASA, it could help shed light on the nature of the moon's activities. Enceladus is Saturn's sixth largest moon, was discovered in 1789 and is 1.272 billion kilometers (0.790 billion miles) away from Earth.
Jets of water shoot out of cracks in the icy shell of Enceladus.
NASA's press release explained that microbes - if there are any that exist there - could combine hydrogen with carbon dioxide dissolved in water to obtain energy.
Our best bet for life beyond Earth may not be a planet, but a moon in our own solar system, NASA announced Thursday.
"It really represents a capstone finding" - or high point - "for the mission", said Linda Spilker, a scientist on the Cassini project who noted that the spacecraft has been circling Saturn for more than a decade.
NASA details that life requires three main ingredients to exist, which includes liquid water, source of energy for metabolism and the right chemical ingredients.
It turns out that Enceladus has every single of those ingredients necessary for the creation and maintenance and evolution of life.
The Cassini spacecraft found hydrogen in the plume of gas and icy material spraying from Enceladus during its last, and deepest, dive through the plume on October 28, 2015.

The strike could also include "could include missiles and bombs, cyber and special operations on the ground", NBC News reported . Chinese Foreign Minister Wang Yi fears a conflict could break out " at any moment " and has warned there would be "no winner".
Plume's composition:Cassini also sampled the plume's composition during flybys earlier in the mission.
The plumes are 98 percent water, scientists said, with traces of molecules including ammonia, carbon dioxide and methane.
Phosphorus and sulfur are needed for life and have not been detected by Cassini, but scientists think they are there because the core of Enceladus is thought to be similar chemically to meteorites that contain the elements, NASA reported.
After orbiting Saturn for 13 years, its "grand finale" mission will end in September when it is diverted to crash into Saturn.
The second study of Europa is based on observations by the Hubble Space Telescope, and is published in the journal Astrophysical Journal Letters.
According to William Sparks of the Space Telescope Science Institute, the Hubble Space Telescope captured pictures of a plume emanating from the same hot spot both in 2014 and in 2016 that were nearly identical in appearance. The Europa plumes appear to be rising from an unusually warm region in the moon's icy crust, indicating that it could be the result of water emanating from the moon's interior.
The administration plans to send a spacecraft called Clipper to Jupiter's water-covered moon Europa in the 2020s to investigate whether conditions there are suitable for life.
