Geysers on Saturn's icy moon Enceladus may form from a 'mushy zone'

Summary

Nutrition label

87% Informative

Enceladus's geyser-like jets release ice and water vapor hundreds of kilometers into space from its south pole.

NASA 's Cassini spacecraft identified these jets in 2005 , before going on to sample them in 2008 , 2009 and 2015 .

A large subsurface ocean, spanning approximately 20 million km3, has commonly been thought to be the primary source of the geysers.

However, new modeling research by Professor Colin Meyer , of Dartmouth College , U.S. , has offered support for an alternative explanation.
