Scientists find source of Saturn ring

[Jay-qu]

LONDON, England (UPI) -- An international team of scientists has found that the source of Saturn`s outer ring is water vapor from the planet`s moon Enceladus.

 

In an article in the journal Science, the researchers say that a plume of water vapor from Enceladus`s south pole has also given the moon a water-based atmosphere. They believe that internal processes within the moon are generating heat to produce the vapor.

 

The outer ring, known as the E-ring, stretches between the orbits of the moons Mimas and Titan. It is composed of microscopic particles.
