Mapping Bennu

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

Hidden details of our home galaxy — the Milky Way — are revealed in different wavelengths. 

Sir Arthur C. Clarke's video greeting to NASA's Jet Propulsion Laboratory for Cassini's first close Iapetus flyby in 2007.

New science, mined from the archives. Data from NASA's Galileo orbiter launched a generation ago yields new evidence of plumes, eruptions of water vapor, from Jupiter's moon Europa.

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.

What incredible things will the Cassini spacecraft at Saturn see and do over the next few years?

NASA's Cassini scientists waited years for the right conditions to produce the first movie that shows lightning on another planet - Saturn.

One of the glittering trails caused by small objects punching through Saturn's F ring is highlighted in this movie from NASA's Cassini spacecraft.

Watch the NASA-JPL press briefing announcing Cassini's final orbits recorded at JPL on April 4, 2017.

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. 

JPL's Dawn mission is en route to rendezvous with the main-belt asteroids Vesta and Ceres, and is using ion propulsion to get there.

Mating of LVA

After a 15-year wait, equinox arrived at Saturn and Cassini was there to witness the spectacle of light and shadow.

Clara, Sugar Plum Fairy, move aside. Saturn's moons give Tchaikovsky's classic ballet, "The Nutcracker," a graceful new spin in this video compiled from some 61 images taken by the Cassini spacecra...

Ranger 9 was the last of the Ranger series of spacecraft launched in the 1960s to explore the moon and was designed to image and impact the moon's crater Alphonsus. This video from 1965 includes im...

On Earth, the ocean floor is home to hydrothermal vents that spout hot water, nourishing life in an otherwise inhospitable environment. Scientists think similar vents could exist on other worlds.

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

In this movie, strung together from a series of images provided by the framing camera on NASA's Dawn spacecraft, we see a full rotation of Vesta, which occurs over the course of roughly five hours. 

This animated movie shows the simulated solar wind velocity from March 21 to May 10, 2013. 

This visualization shows the orbits of NASA-related near-Earth science missions that are considered operational as of March 2017. 

This animation demonstrates how deformation in the icy surface of Europa could transport subsurface ocean water to the moon’s surface.

This movie shows clouds in the mid-southern latitudes of Saturn's largest moon, Titan, in a series of images captured by NASA's Cassini spacecraft a few months after fall began in the southern hemi...

This animation glides along the shoreline of Ontario Lacus, the largest lake on the southern hemisphere of Saturn’s moon Titan.

Cassini's mission planners created this animation to showcase the mission's final orbits, known as the Grand Finale.

The shadow of Saturn's moon Tethys seems to disappear as it crosses the planet's rings, demonstrating variations in the density of particles across the rings.
