Cassini finds activities on the Saturn's moon, Dione

Dear followers,

The +NASA Cassini spacecraft which explores activities on Dione since 2004 has found some interesting data. The following picture, obtained from Cassini, shows the topography of a mountain known as Janiculum Dorsa on the Saturn's moon, Dione.

Scientists have found more evidence for the idea that Dione was likely active in the past. It could still be active now.

Actually, "A picture is emerging that suggests Dione could be a fossil of the wondrous activity Cassini discovered spraying from Saturn's geyser moon Enceladus or perhaps a weaker copycat Enceladus," said Bonnie Buratti of +NASA Jet Propulsion Laboratory in Pasadena, California, who manages the Cassini science team that studies icy satellites. The presence of a subsurface ocean on Dione would boost the astrobiological potential of this once-boring iceball.

Many other little moons in our solar system thought to have a subsurface ocean, such Saturn's moons Enceladus and Titan and Jupiter's moon Europa which are among the most geologically active worlds in our solar system.

Huge hurricane on Saturn, first time in color

The spacecraft Cassini, sent by +NASA  has provided scientists of the +NASA Jet Propulsion Laboratory  the first close-up, visible-light views of a behemoth hurricane swirling around Saturn's north pole. The Cassini-Huygens mission is a cooperative project of +NASA , the +European Space Agency, ESA and the Italian Space Agency.
High-resolution pictures and video indicated the hurricane's eye is about 1,250 miles wide, 20 times larger than the average hurricane eye on Earth.
