Jupiter’s Volcanic Moon Io
During its close flyby of Jupiter’s moon Io on December 30, 2023, NASA’s Juno spacecraft captured some of the most detailed imagery ever of Io’s volcanic surface. In this image, taken by the JunoCam instrument from about 930 miles (1,500 kilometers) above the moon, Io’s night side [left lobe] is illuminated by “Jupitershine,” which is sunlight reflected from the planet’s surface. This…

Juno Detected the Final Missing Auroral Signature from Jupiter’s Four Largest Moons
Jupiter hosts the brightest and most spectacular auroras in the Solar System. Near its poles, these shimmering lights offer a glimpse into how the planet interacts with the solar wind and moons swept by Jupiter’s magnetic field. Unlike Earth’s northern lights, the largest moons of Jupiter create their own auroral signatures in the planet’s atmosphere — a phenomenon that Earth’s…

NASA Shares How to Save Camera 370-Million-Miles Away Near Jupiter
An experimental technique rescued a camera aboard the agency’s Juno spacecraft, offering lessons that will benefit other space systems that experience high radiation. The mission team of NASA’s Jupiter-orbiting Juno spacecraft executed a deep-space move in December 2023 to repair its JunoCam imager to capture photos of the Jovian moon Io. Results from the long-distance save were presented during a…

Jupiter’s Turbulent Atmosphere
JunoCam, the visible light imager aboard NASA’s Juno spacecraft, captured this view of Jupiter’s northern high latitudes during the spacecraft’s 69th flyby of the giant planet on Jan. 28, 2025. Jupiter’s belts and zones stand out in this enhanced color rendition, along with the turbulence along their edges caused by winds going in different directions. The original JunoCam data used to…

Danish Instrument Helps NASA’s Juno Spacecraft See Radiation
Using cameras designed for navigation, scientists count ‘fireflies’ to determine the amount of radiation the spacecraft receives during each orbit of Jupiter. Scientists with NASA’s Juno mission have developed the first complete 3D radiation map of the Jupiter system. Along with characterizing the intensity of the high-energy particles near the orbit of the icy moon Europa, the map shows how…

NASA’s Juno Mission Captures the Colorful and Chaotic Clouds of Jupiter
During its 61st close flyby of Jupiter on May 12, 2024, NASA’s Juno spacecraft captured this color-enhanced view of the giant planet’s northern hemisphere. It provides a detailed view of chaotic clouds and cyclonic storms in an area known to scientists as a folded filamentary region. In these regions, the zonal jets that create the familiar banded patterns in Jupiter’s…

NASA’s Juno Provides High-Definition Views of Europa’s Icy Shell
Imagery from the solar-powered spacecraft shows some intriguing features on the ice-encased Jovian moon. Images from the JunoCam visible-light camera aboard NASA’s Juno spacecraft supports the theory that the icy crust at the north and south poles of Jupiter’s moon Europa is not where it used to be. Another high-resolution picture of the icy moon, by the spacecraft’s Stellar Reference…

Just in Time for Halloween, NASA’s Juno Mission Spots Eerie “Face” on Jupiter
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 Jet N7. The image shows turbulent clouds and storms along Jupiter’s terminator, the dividing line between the day and night sides of the planet. The low angle of sunlight highlights the complex topography…

NASA to Host Briefing to Reveal New Findings from Jupiter’s Atmosphere
NASA will hold a virtual media briefing at 3 p.m. EDT Thursday, Oct. 28, to discuss the latest results from the agency’s Juno spacecraft. The science team will reveal new findings that provide the first 3D look at how the planet’s roiling atmosphere operates underneath the top layers of clouds, and how these revelations offer insight into the atmospheres of…
