This three-frame animation from NASA's Cassini spacecraft shows the swirling clouds in a vortex spawned by a great northern storm on Saturn. The clouds are moving in a clockwise direction.

Lucy will be the first mission to explore the Trojan asteroids – small bodies left over from the formation of the solar system.

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

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

As millions of people observed the total lunar eclipse on October 8, 2014, MESSENGER was also watching from Mercury.

NASA’s Psyche team will measure the asteroid’s magnetic field using a magnetometer. This instrument is composed of two identical high-sensitivity magnetic field sensors located at the middle and ou...

The animation archived on this page shows the geocentric phase, libration, position angle of the axis, and apparent diameter of the Moon throughout the year 2017, at hourly intervals.

A simulated flyover of the most intriguing landmarks on giant asteroid Vesta, as seen by NASA's Dawn spacecraft.

With Cassini’s exploration of Saturn coming to a dashing end in a few months, the mission team scheduled an “All Cassini Plus Alumni” group photo on Wednesday, June 21,2017 to commemorate the event. 

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

A new video from NASA's Dawn spacecraft takes us on a flyover journey above the surface of the giant asteroid Vesta.

This artist's concept shows "tides" on Titan raised by Saturn's gravity, as detected by NASA's Cassini spacecraft.

Look up to the night sky just before dawn, or after dusk, and you might see a faint column of light extending up from the horizon. That luminous glow is the zodiacal light, or sunlight reflected to...

As Huygens descends Titan's atmosphere, Cassini will record the data from 72,000 kilometers (about 44,700 miles).

This short computer-animated film highlights Cassini's accomplishments and Saturn and reveals the science-packed final orbits between April and September 2017.

Ceres' lack of giant impact basins presents a puzzle to scientists.

This visualization of the Apollo 17 landing site uses real lunar orbiter data to retrace the paths of the astronauts during their three days of exploration.

Cassini stares deep into the swirling hurricane-like vortex at Saturn's south pole, where the vertical structure of the clouds is highlighted by shadows. 

OSIRIS-REx has imaged Bennu in higher resolution than we have Earth and our own Moon. Since its arrival at the asteroid on Dec. 3, 2018, the spacecraft has discovered boulders the size of buildings...
