New data from NASA's Cassini spacecraft may solved a longstanding mystery. The length of a day on Saturn: 10 hours, 33 minutes and 38 seconds.

New measurements of the mass of Saturn's rings reveal their age — and something they have in common with dinosaurs.

New NASA research confirms that Saturn's rings are being pulled into Saturn by gravity as a dusty rain of ice particles under the influence of Saturn’s magnetic field.

November 16 marks the premiere of a unique film and musical experience inspired by the Hubble Space Telescope’s famous Deep Field image

November brings planets, an asteroid, a comet and the Leonids meteor shower.

From deep below the soil at Earth’s polar regions to Pluto’s frozen heart, ice exists all over the solar system...and beyond.

Cassini's Grand Finale orbits pay off: Final dives tell the story of the previously unexplored region between Saturn and its rings

Quite a few candles have been lit since NASA was born on Oct. 1, 1958. Here’s a quick look back at some highlights from six decades of exploration—and a glimpse of what’s ahead.

The Cassini spacecraft has been gone for a year now, but the science continues. Here are 10 reasons why Cassini mattered...

A study using Cassini data reveals a warming, high-altitude, hexagonal vortex emerging at Saturn’s northern pole

The Cassini mission revealed a surprising feature emerging at Saturn's northern pole as it nears summertime: a warming, high-altitude vortex with a hexagonal shape, akin to the famous hexagon seen deeper down in Saturn's clouds.

The final Cassini Science Symposium, and other recent Cassini mission events.

To most of us, dust is an annoyance. But these tiny particles that float about and settle on surfaces play an important role across the solar system.

This summer offers plenty of opportunities for skywatchers looking to observe Mars, Saturn, Jupiter and meteors--with or without a telescope.

The Academy of Television Arts & Sciences nominated NASA's Jet Propulsion Laboratory in Pasadena, California, for Outstanding Original Interactive Program for its coverage of the Cassini mission's Grand Finale at Saturn, including news, web, education, television and social media efforts.

New research from NASA’s Cassini spacecraft’s up-close Grand Finale orbits shows a surprisingly powerful and dynamic interaction of plasma waves moving from Saturn to its rings and its moon Enceladus.
