Planetary science: Cracks under stress
Andrew J. Dombard1
Abstract
Two modelling studies provide complementary descriptions of how gravitational forces might help to form the plumes of water vapour that spout from cracks in Enceladus, one of Saturn's icy moons.
Enceladus, an icy satellite of Saturn only about 500 kilometres in diameter, is a remarkably active body1, 2, 3. NASA's Saturn orbiter, Cassini, observed plumes composed mostly of water, presumed to be spouting from a set of nearly parallel cracks, nicknamed the 'tiger stripes'.
