Fountains Discovered on Saturn's Enceladus
Explanation:
Fountains of ice shoot out from Saturn's moon Enceladus.
Clear
discovery
images
of the fountains were made using observations from the
robot Cassini spacecraft
currently orbiting
Saturn
.
During a recent pass, Cassini was programmed to look back toward
the Sun where
Enceladus
would appear as a thin
crescent
.
From this vantage point, particles emitted from the surface
would better show themselves by reflecting sunlight.
The tactic was successful --
the above frame
shows several plumes emanating from
regions
previously known
to contain gashes in the surface dubbed
tiger stripes
.
Cassini detected an increase in particle emissions from these
regions during a July flyby.
Some of these ice particles likely contribute to the make up of Saturn's
mysterious E ring
.
