NASA's Cassini spacecraft has revealed the presence of ammonia on Saturn's icy moon Enceladus.

If there is an underground ocean on Enceladus, then ammonia would be vital to it. Ammonia acts as an antifreeze, allowing water to remain liquid at temperatures as low as –97 degrees Celsius . This is the first time that scientists have found ammonia on an icy satellite of a giant planet.

In my previous post Happy Halloween from Cassini Spacecraft Team i mentioned about Cassini spacecraft going to the Moon of Saturn, Enceladus on 2th November, 2009.

Cassini has captured some amazing images of the plumes shooting from Enceladus , they are simply the raw images.

The objective of Cassini is to analyse the particles in the plume with the instruments that can detect the mass , size, charge, speed and composition.

These are the first images of the plume and are amazing.
