JunoCam

On a recent flyby, the Juno spacecraft spotted intense volcanic activity on Io, one of Jupiter's moons. It was more extreme than any volcanism ever seen on Io. The post Juno spots most extreme volcanic activity on Io to date first appeared on EarthSky.

During a close flyby of Europa, the Juno spacecraft was at an altitude of just 330 kilometers (220 miles) above the moon's surface. It caught some awesome...

Squint.

The high-resolution pictures, taken during Juno's flyby of Europa on September 29, 2022, seem to support the true polar wander theory – that Europa's ice shell is...

The best-yet map of active volcanoes on Jupiter's moon Io hints at a hidden magma ocean—and more

NASA's Juno spacecraft has encountered an eerie sight!

On Sept. 7, 2023, during its 54th close flyby of Jupiter, NASA's Juno mission captured this view of an area in the giant planet's far northern regions called

Jupiter's ocean moons capture most of our attention because of their potential habitability. But Io, Jupiter's bad-boy volcanic moon, is in a class of its own. There's nothing else like it in the solar system, and NASA's Juno spacecraft captured new images of the volcanic satellite during its closest approach yet.

NASA's Juno spacecraft has snapped a pic of a giant planet and its moon.

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.

NASA's Juno mission is set to photograph more views from this moon on Dec. 15.

These images of Jupiter's icy moon Europa were taken by the JunoCam instrument aboard NASA's Juno spacecraft during a close approach on September 29, 2022.

A NASA probe will swoop to around 350 kilometres above Europa's surface on 29 September, returning detailed images and data on its magnetic fields and icy crust

The newly-discovered volcanic hotspot is larger than Earth's Lake Superior, and belches out eruptions six times the total energy of all the world's power plants.

Jumping Jupiter! The results are in, storm chasers! Thanks to your help over the last two years the Jovian Vortex Hunter project has published a catalog of 7222 vortices, which you can download here. Each vortex is an enormous swirling windstorm in Jupiter's atmosphere–terrifying yet beautiful to behold. The vortices are labeled by color ("white" […]

A photograph shared on social media in early November 2024 was taken by NASA and showed the planet Jupiter.

Planetary geologist Erin Leonard of NASA talks about the Europa Clipper mission – and how to see if the icy moon of Jupiter has conditions required to support life.

Jupiter's moon Io has a new volcano! The volcano appears in Juno spacecraft images from February 2024. Streams of lava and sulfur stains mark its flanks. The post Jupiter's moon Io has a new volcano! See pics here first appeared on EarthSky.

NASA's Juno spacecraft saw molten rock on Jupiter's moon Io

Saturday's flyby provided NASA with many raw images, which it released to citizen scientists for post-processing. Juno's close pass allowed for outstanding high-resolution photos (above and below)...
