This page showcases our resources for those interested in learning more about Jupiter.

Science instruments and other hardware for the spacecraft will come together in the mission’s final phase before a launch to Europa in 2024.

A new study finally reveals higher-frequency X-rays and explains why they eluded another mission 30 years ago.

Europa Clipper will need to know its orientation while traveling from Earth to Jupiter and in orbit around Jupiter. To accomplish this, it will use the stars.

The Next Full Moon is the Wolf Moon, Ice Moon, the Moon after Yule, and the Old Moon.

Our 2021 round-up of NASA planetary science is packed with the year’s most spectacular images, ground-breaking discoveries, and incredible mission events.

NASA's Juno spacecraft captured sounds of Jupiter's moon Ganymede during a June 7, 2021, close flyby.

Finding plumes at Europa is an exciting prospect, but scientists warn it’ll be tricky, even from up close.

NASA’s Hubble Space Telescope has completed this year's grand tour of the outer solar system.

During its 36th low pass over Jupiter, NASA’s Juno spacecraft captured this view of striking Jupiter's cloud bands and swirls.

NASA Administrator Bill Nelson laid out the path forward for early Artemis missions that will pave the way for lunar surface missions.

New Juno findings provide a fuller picture of Jupiter’s colorful atmospheric features, and offer clues about what's below the clouds.

NASA scientists are calling for a framework that provides context for findings related to the search for life.

JPL's lucky peanuts are an unofficial tradition at big mission events.

Hubble observations of Europa have revealed the presence of persistent water vapor – but, mysteriously, only in one hemisphere.

Winds in the outermost "lane" of Jupiter's Great Red Spot are accelerating – a discovery made possible by Hubble.

In 2023, NASA’s Volatiles Investigating Polar Exploration Rover (VIPER) will land near the western edge of the Nobile Crater at the Moon’s South Pole.

The rover will be delivered to the Moon's surface in late 2023. VIPER is the first resource-mapping mission on the surface of another celestial body.

The Next Full Moon is the Harvest Moon, the Fruit Moon, the Barley Moon, and the Corn Moon.

Juno used its infrared instrument during recent flybys of Ganymede to create this map a decade after Juno’s launch.

This week in 2011, the Juno mission to Jupiter launched from NASA’s Kennedy Space Center aboard an Atlas V-551 rocket.

The shadows cast by the roughness of the Moon’s surface create small cold spots for water ice to accumulate even during the harsh lunar daytime.

For the first time, astronomers have uncovered evidence of water vapor in the atmosphere of Jupiter's moon Ganymede.

NASA has selected SpaceX to provide launch services for Earth’s first mission to conduct detailed investigations of Jupiter's moon Europa.

The next full Moon goes by many names including the Buck Moon.
