NASA's Juno spacecraft will come closer to Jupiter's moon Io on Dec. 30 than any spacecraft has in 20 years, getting a good look at the solar system's most volcanic body.

An aging spacecraft more than a decade into its mission may soon undertake one of the most ambitious maneuvers in modern space exploration. According to a detailed study published on arXiv, a team of ...

Juno was originally set for a fiery death in Jupiter's atmosphere in 2021, but NASA extended its mission through September 2025 so it could observe Ganymede, Io, and Europa more closely.

"Juno first entered safe mode at 5:17 a.m. EDT, about an hour before its 71st close passage of Jupiter — called perijove," NASA said in a statement. "It went into safe mode again 45 minutes ...

Juno has also recently been imaging Jupiter’s innermost moo, Io. This world is, the most volcanic in the solar system, with eruptions orders of magnitude bigger than anything similar on Earth.

As of this most recent flyby, NASA says that the Juno space probe has flown over 510 million miles, documenting close encounters with three of Jupiter’s four largest moons during that time. This ...

Juno has performed more than 50 flybys of Jupiter and flown more than 510 million miles. It arrived at Jupiter on July 4, 2016, with the first science flyby occurring 53 days later.

When NASA’s Juno spacecraft pointed a sensitive instrument toward the belly of the largest planet in the Solar System, it detected something peculiar: A jet hidden deep below Jupiter’s atmosphere.

Today at exactly 9:57 and 48 seconds a.m. PDT, NASA’s Juno spacecraft was 5.5 million miles (8.9 million kilometers) from its July 4th appointment with Jupiter. Over the past two weeks, several ...

During its 51st orbit of Jupiter on Tuesday, May 16, NASA's Juno spacecraft imaged Io, the most volcanic body in the solar system from just 22,060 miles—the closest yet.

After an almost five-year journey to the solar system’s largest planet, NASA’s Juno spacecraft successfully entered Jupiter’s orbit during a 35-minute engine burn. Confirmation that the burn ...

The Juno spacecraft made its 49th close flyby of Jupiter earlier this year, and NASA has shared stunning images taken as it whizzed by the planet's cloud tops.
