Europa

Jupiter's turbulent southern hemisphere captured by NASA's Juno spacecraft after a close flyby of the gas giant planet on Dec. 21, 2018.

Upcoming 16th science pass of Jupiter marks Juno’s halfway point in prime mission data collection.

JunoCam data has detected atmospheric wave trains, towering atmospheric structures that trail one after the other as they roam the planet

From deep below the soil at Earth’s polar regions to Pluto’s frozen heart, ice exists all over the solar system...and beyond.

Quite a few candles have been lit since NASA was born on Oct. 1, 1958. Here’s a quick look back at some highlights from six decades of exploration—and a glimpse of what’s ahead.

September nights! Planets bright! Milky Way sights!!

Is there water deep in Jupiter's atmosphere, and if so, how much?

To most of us, dust is an annoyance. But these tiny particles that float about and settle on surfaces play an important role across the solar system.

Simulating alien worlds, designing spacecraft with origami and using tiny fossils to understand the lives of ancient organisms are all in a day’s work for NASA interns.

New comprehensive mapping of the radiation pummeling Jupiter’s icy moon Europa reveals where scientists should look -- and how deep they’ll have to go -- when searching for signs of habitability and biosignatures.

This summer offers plenty of opportunities for skywatchers looking to observe Mars, Saturn, Jupiter and meteors--with or without a telescope.

Twelve new moons orbiting Jupiter have been found—11 “normal” outer moons, and one that they’re calling an “oddball.” This brings Jupiter’s total number of known moons to a whopping 79.

NASA’s Juno mission arrived at the King of Planets in July 2016. The intrepid robotic explorer has been revealing Jupiter's secrets ever since. Here are 10 historic Juno mission highlights.

In a new paper published in Nature today, scientists from NASA’s Juno mission describe the ways in which lightning on Jupiter is actually analogous to Earth’s lightning. Although, in some ways, the two types of lightning are polar opposites.

NASA has approved an update to Juno’s science operations until July 2021. This provides for an additional 41 months in orbit around Jupiter and will enable Juno to achieve its primary science objectives.

NASA and its partners are blending ocean and space exploration, with a project called SUBSEA, short for Systematic Underwater Biogeochemical Science and Exploration Analog. Lessons learned in both fields will be mutually beneficial and could help design future science-focused missions across the solar system.

NASA will host a Science Chat May 14 about the latest analysis of Jupiter’s moon Europa and its status as a promising place in the solar system to search for life.

Resurrected data from Galileo’s first flyby of Ganymede is yielding new insights about the moon’s environment — which is unlike any other in the solar system.

This image of Jupiter’s iconic Great Red Spot and surrounding turbulent zones was captured by NASA’s Juno spacecraft.

Legendary explorers and visionaries, real and fictitious, are among those immortalized in the first set of official surface-feature names for Pluto's largest moon, Charon.

A 3-D infrared movie depicts cyclones and anticyclones in Jupiter's polar regions, and the first detailed view of a dynamo powering the magnetic field of a planet beyond Earth.

The Moon, Mars and Saturn form a pretty triangle in early April, Lyrid meteors are visible, and more.

This year, NASA will launch two satellite missions that will increase our understanding of Earth’s frozen reaches. This week’s #10Things is all about ice.

Though once big enough to swallow three Earths with room to spare, Jupiter’s Great Red Spot has been shrinking for a century and a half.

Whether you're doing it for the nerd cred or the pie, this week on #10Things, we've got all the ways you can celebrate #PiDay with NASA.
