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.

On April 9, 2022, the JunoCam instrument captured what it would look like to ride along with the Juno spacecraft.

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.

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

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

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.

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.
