NASA scientists pioneered new techniques to effectively peer beneath Greenland's thick ice sheet and into the crust itself.

Astronomy highlights for February 2020: it's the best time of the year to view Mercury; Mars disappears behind the Moon; and the bright red star on Orion’s shoulder, Betelgeuse, has been acting wei...

This animation based on data obtained by NASA’s Cassini spacecraft shows how the “explosions” of hot plasma on the night side (orange and white) periodically inflate Saturn’s magnetic field (white ...

This animated graphic shows how Saturn and its moon Enceladus are electrically linked.

This video describes Cassini measurements of high speed streams of tiny dust particles emanating from the vicinity of Saturn.

With kaleidoscopic forms and hues, these two false-color views from NASA's Cassini spacecraft show the patterns that come and go in the course of one Saturn day within the huge storm in the planet'...

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.

Rotating asteroids have a tough time sticking to their orbits. Their surfaces heat up during the day and cool down at night, giving off radiation that can act as a sort of mini-thruster.

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.

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

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.

This new animation shows us that Saturn's moon Titan has more in common with Earth than we thought.

What’s the latest news from Mars? NASA’s InSight lander and MarCO CubeSats are on their way to the Red Planet, a tiny helicopter will hitch a ride with the Mars 2020 rover mission, and Curiosity’s ...

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.

Cassini mission leads Earl Maize and Linda Spilker talked about the spacecraft's epic journey and science - and the exciting two-part grand finale.

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.

WE. ARE. NASA. And after 60 years, we're just getting started.

Go, Atlas. Go, Centaur. Go, InSight! NASA's InSight mission launched from Vandenberg Air Force Base for Mars on May 5, 2018—the first interplanetary launch from the West Coast. 

This visualziation shows the major fragments of comet Showmaker-Levy 9 colliding with Jupiter in 1994.

NASA's Cassini spacecraft discovered hydrogen in the plume of gas and icy particles spraying from Saturn's moon Enceladus. The discovery means the small, icy moon — which has a global ocean under i...

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 ...

Orange and white stripes slide against each other, and huge oval storms  gyrate in the NASA's Cassini spacecraft's first color movie clip of Jupiter.  

NASA's Cassini spacecraft, in orbit around Saturn for nearly 13 years, is beginning its Grand Finale — and it's thanks to some Crazy Engineering!  A team of engineers called astrodynamicists use ma...

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