This processed image of Io by New Horizons shows the 290-kilometer-high (180-mile-high) plume of the volcano Tvashtar near Io’s north pole. Also visible is the Prometheus volcano’s much smaller plume in the 9 o’clock direction. The top of the Masubi volcano’s plume appears as an irregular bright patch near the […]

Ganymede flyby. Credit: NASA The probe flew closer to Jupiter’s largest moon, Ganymede, than any other spacecraft in more than two decades, offering dramatic glimpses of both the icy orb and the gas giant. On June 7, 2021, NASA’s Juno spacecraft flew closer to Jupiter’s ice-encrusted moon Ganymede than any […]

“Clyde’s Spot” on Jupiter imaged by Juno on April 15, 2021. Image data: NASA/JPL-Caltech/SwRI/MSSS. Image processing by Kevin M. Gill © CC BY­­. During its 33rd low pass over the cloud tops of Jupiter on April 15, 2021, NASA’s Juno spacecraft captured the intriguing evolution of a feature in the giant planet’s atmosphere known […]

The SwRI-led Ultraviolet Spectrograph (UVS) orbiting Jupiter aboard NASA’s Juno spacecraft allowed scientists to discover faint aurora features likely triggered by charged particles coming from the edge of Jupiter’s massive magnetosphere. This occurrence, shown in the false color series of images recorded 30 seconds apart (red panels), displays the characteristically […]

An illustration shows NASA’s Juno spacecraft as it entered orbit of Jupiter on July 4, 2016, after traveling for nearly five years and more than 1.7 billion miles. Credit: NASA/JPL/SwRI Data from the NASA spacecraft’s journey to Jupiter suggests that Mars may be shedding dust into interplanetary space. Look up to the night sky just before […]

An artist’s concept of the Juno spacecraft in orbit around Jupiter. Credit: NASA The spacecraft, which has been gathering data on the gas giant since July 2016, will become an explorer of the full Jovian system – Jupiter and its rings and moons. NASA has authorized a mission extension for its Juno spacecraft […]

In this animated GIF, the clouds on the periphery of some of Jupiter’s polar cyclones rotate counterclockwise, while the core of the cyclones rotate clockwise. The JunoCam images used for this animation were taken from altitudes of about 18,000 miles (28,567 kilometers) above Jupiter’s cloud tops. Citizen scientist Gerald Eichstädt […]

This illustration uses data obtained by NASA’s Juno mission to depict high-altitude electrical storms on Jupiter. Juno’s sensitive Stellar Reference Unit camera detected unusual lightning flashes on Jupiter’s dark side during the spacecraft’s close flybys of the planet. Credit: NASA/JPL-Caltech/SwRI/MSSS/Gerald Eichstädt The spacecraft may have found where the colorless gas […]
