Streaking through space at 19,000 mph, NASA's Cassini probe will pass just 30 miles above the south pole of Saturn's moon Enceladus Wednesday, flying through tenuous geyser-like plumes of ice ...

In addition to Waite and Glein, the authors of the Science study, “Cassini Finds Molecular Hydrogen in the Enceladus Plume: Evidence for Hydrothermal Processes,” include Rebecca Perryman, Ben ...

The NASA/ESA/ASI Cassini-Huygens mission has directly sampled the water plumes jetting into space from Saturn’s moon Enceladus. The findings from these fly-throughs are the strongest evidence ...

According to recent analysis, water vapor plumes erupting from cracks in Enceladus’ icy shell have a pH between 10.1 and 11.6 ...

It's been a busy year for Cassini, making observations of Hyperion and Dione, before discovering evidence of a global ocean beneath the moon Enceladus' icy surface. Now the probe is back at ...

NASA's Cassini spacecraft has observed Enceladus' tiger stripe vents behaving in a way that will force astronomers to rethink their current models regarding the enigmatic moon's internal plumbing.

Just in time for Halloween, NASA has released ghostly images of the icy geysers shooting out of Saturn’s moon Enceladus. More data taken during the Cassini spacecraft’s deepest-ever dive ...

NASA's Cassini spacecraft will sample the ocean of Saturn's moon Enceladus on Wednesday, Oct. 28, when it flies through the moon's plume of icy spray.
