Is There Liquid Water On One Of Saturn's Moons?

A recent research, published in the journal Nature on Wednesday, shows huge plumes of water vapor and ice particles that spew from Saturn’s moon, Enceladus, at supersonic speeds, in a way that certainly suggests they come from liquid water down below the icy surface.

This is a new piece of evidence that the moon may harbor an underground ocean of water that leads to the conclusion that it might support life, even if microbial organisms only. In a telephone interview, Candice Hansen, the leader of the study, said: "This is more evidence that there is liquid water there. You also need energy, you need nutrients, and you need organics. It looks like the pieces are there. Whether or not there's actually life, of course, we can't say.”

The spacecraft Cassini discovered humongous geysers erupting from fissures near the south pole of Enceladus into space in 2005. Enceladus is one of about 60 moons of the ringed planet Saturn. The data collected last year by Cassini’s Ultraviolet Imaging Spectrograph instrument helped researchers conclude that the behavior of the plumes supports a mathematical model in which the cracks that extend below the surface act as nozzles that channel water vapor from an underground liquid water reservoir. The geysers shoot plumes into space at more than 1,300 mph.

The Cassini spacecraft, operated in a joint U.S.-European mission, flew close over the surface of Enceladus in March and through a plume, collecting samples of ice and gas. With this discovery, there are now three places which have liquid water near the surface, the Earth, Jupiter’s moon Europa and now Saturn’s Enceladus.” This is another attempt for scientists to find a habitable place near Earth, and that’s because life on this planet will pretty soon become very hard. The Mars Lander has also found pieces of ice on Mars, which made researchers think Mars could support life.
