Saturn

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

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.

What's up in the night sky this month? Enjoy a ringside seat for Saturn, plus a night long parade featuring Venus, Jupiter, Mars and Vesta!

Members of the Cassini flight team are honored to be receiving so many formal accolades for the 20-year mission's accomplishments, while even more were awarded this month.

The Moon, Mars and Saturn form a pretty triangle in early April, Lyrid meteors are visible, and more.

At the 49th Lunar and Planetary Science Conference in March 2018, Cassini Project Scientist Linda Spilker reviewed the highlights of the Cassini mission.

At sunset, catch elusive Mercury, bright Venus, the Zodiacal Light, Mars, Saturn, and Jupiter between midnight and dawn.

From the spacecraft’s final year, we couldn’t pick just 10! Here are the stand-out images of 2017, as chosen by the Cassini team.

Several solar system exploration missions routinely publish raw, unprocessed images taken by cameras aboard robotic spacecraft. Unlike most pictures that appear on NASA web sites, these images are not validated or calibrated, and often lack captions and other information to provide context.

Just as the oceans on Earth do, the hydrocarbon seas on Saturn's moon Titan lie at an average elevation.
