Unveiling Rogue Planets

Earth's Moon  

The little moon Daphnis and its entourage of waves on the edge of the Keeler gap in Saturn's rings cast long shadows in this movie created from images taken as the planet approaches its mid-August ...

In this movie from NASA's Cassini spacecraft, the gravitational pull of Saturn's moon Prometheus creates patterns in Saturn's F ring.

Ben Holt tells how he fell in love with the ocean as a teenager and how that lead to a career as a research scientist.

Giovanni Cassini, the astronomer, discovers a moon near Saturn. Half is dark as coal. The other half, bright as snow. Three centuries later, Cassini, the spacecraft, flies by for a close look.

For 13 years the spacecraft’s incredible, truly otherworldly images have revealed the wonder of Saturn in surprising, often awe-inspiring ways.

NASA's Cassini spacecraft has spotted a glowing patch of ultraviolet light near Saturn's north pole that marks the presence of an electrical circuit that connects Saturn with its moon Enceladus.

This image shows that NASA's Dawn mission detected abundances of hydrogen in a wide swath around the equator of the giant asteroid Vesta. The hydrogen probably exists in the form of hydroxyl or wat...

On Nov. 30, 2016, NASA's Cassini mission begins a daring set of ring-grazing orbits, skimming past the outside edge of Saturn's main rings.

This movie, built with data collected during the European Space Agency's Huygens probe on Jan. 14, 2005, shows the operation of the Descent Imager/Spectral Radiometer camera during its descent and ...

How can you communicate with Mars spacecraft when the Sun is in the way? Learn more about 'solar conjunction' in this 60-second video.

This still from a movie shows an image taken by NASA's Dawn spacecraft layered on a digital terrain model of an unusual hill containing a dark-rayed impact crater and nearby dark deposit on asteroi...

This movie presents a series of animations showing NASA's Dawn spacecraft traveling to and operating at the giant asteroid Vesta.

Dr. Bonnie Buratti describes her background as well as her role as a senior research scientist.

This infrared movie from NASA's Cassini mission shows the churning of the curious six-sided jet stream at Saturn's north pole known as "the hexagon."

What's Up for January? Morning meteors, Mars meets its "rival," and the Moon comes around for another visit with Venus.

NASA's Cassini spacecraft made its final approach to Saturn and dove into the planet’s atmosphere on Friday, Sept. 15, 2017 but the science provided by this enduring spacecraft will live on.

Hello from Saturn, essentially on the opposite side of the sun as seen from Earth! This annual occurrence called solar conjunction, when Saturn (and Cassini) nearly disappear behind the sun.

Flight across Titan

The geocentric phase, libration, position angle of the axis, and apparent diameter of the Moon throughout the year 2020.

This sequence of images shows the Sun from its surface to its upper atmosphere and in order of temperature from the first one at 6,000 degrees C on the surface out to about 10 million degrees C.

The flight over Charon begins high over the hemisphere New Horizons saw on its closest approach, then descends over the deep, wide canyon of Serenity Chasma. 

Vesta and Ceres reside in the boundary area of the asteroid belt, where the composition of bodies changes from being almost dry to showing the effects of hydration.

RTG fit and test

This animation, from Cassini's navigation team, shows the spacecraft's final orbits in 2016 and 2017.
