The most prominent jets of vapor and icy particles emerging from the south polar terrain of Saturn’s moon Enceladus are shown here in graphical form in a movie clip of a “rotating” Enceladus.

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 movie shows Mercury's globe as it rotates. 

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.

With fingers crossed and eyes wide open, sci-fi fans and scientists savor the joys of discovery...at Iapetus.

This movie was built with data collected during the 147-minute plunge through Titan's thick orange-brown atmosphere to a soft sandy riverbed by the European Space Agency's Huygens Descent Imager/Sp...

This movie captured by NASA'S Cassini spacecraft shows a south polar vortex, or a swirling mass of gas around the pole in the atmosphere, at Saturn’s moon Titan.

A simplified visualization of Saturn's magnetic field, or magnetosphere.

The interaction of the solar wind with the Martian moon Phobos creates a complex electrical environment that could impact future exploration.

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.

What's Up for March? Planet-palooza in the morning, a "Sirius" look at the Dog Star, and an evening trio at the end of the month.

What's Up for November? Mercury transits across the Sun, and the dimming of the "Demon star," Algol.

Hello, my name is Janelle. I think the best topic is number 2, Titan.

Part of the shadow of Saturn's moon Mimas appears as if it has been woven through the planet's rings in this unusual series of images from Cassini.

This animation, derived from data obtained by NASA’s Cassini spacecraft, shows how plasma swirling around Saturn is correlated to bursts of radio waves emanating from the planet.

Project Scientist Linda Spilker and Mission Planner Molly Bittner answer questions about Cassini's Ring-Grazing orbits during this Jan. 30, 2017 Facebook Live event. 

This animated sequence of images, captured by NASA's Cassini spacecraft, shows changes in the brightness of the Enceladus plume during a 6.5-hour observation.

As Titan Turns

Mark Hofstadter describes the lure of science -- of discovering something new -- and his path to becoming a planetary scientist.

As NASA marks the 50th anniversary of the Apollo 11 Moon landing, here are five things to know about the Moon that you can share with others.

Change is detected on Saturn’s moon Titan, in these three composite images from data taken during flybys in October 2005, January 2006 and March 2006 by NASA’s Cassini spacecraft.
