Solved: One Mystery Of The Geyser On Enceladus

I was wondering about that!

The raging eruption of dust and water from the south pole of Enceladus, Saturn's sixth-largest moon, has intrigued scientists ever since the Cassini spacecraft provided dramatic images of the phenomenon.

Physicist Nikolai Brilliantov from the University of Leicester and colleagues in Germany, have revealed why the dust particles in the plume emerge more slowly than the water vapour escaping from the moon's icy crust.

Enceladus orbits in Saturn's outermost "E" ring. It is one of only three outer solar system bodies that produce active eruptions of dust and water vapour. Moreover, aside from the Earth, Mars, and Jupiter's moon Europa, it is one of the only places in the solar system for which astronomers have direct evidence of the presence of water.
