The low angle of sunlight along the slim crescent of Saturn's moon Enceladus (313 miles or 504 kilometers across) highlights the many fractures and furrows on its icy surface.

Saturn spacecraft toting CU Boulder instrument starts swan song

Toting a $12 million instrument built by the University of Colorado Boulder, NASA's Cassini spacecraft made the first of 22 dives between the rings of Saturn and the gaseous planet today, the beginning of the end for one ...

Video: Supersonic gas jets blast off

Supersonic gas jets sound like science fiction, but they are actually found throughout our solar system: for example, fast jets of sulfur dioxide stream from the surface of Jupiter's moon Io and water vapor sprays from the ...

Of all the icy moons in the Solar System, Saturn's moon Enceladus is probably the 'hottest' when measured for its potential to host life. Despite its distance from Earth, it may also be the easiest to investigate.

Enceladus dalmatian terrain close-up

During its final close flyby of Saturn's moon Enceladus, NASA's Cassini spacecraft revisited a landscape, and a mystery, that it had originally glimpsed more than 10 years earlier.
