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 […]

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 […]

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 […]

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. […]

NASA’s Juno Back to Normal Operations After Entering Safe Mode

The spacecraft was making its 71st close approach to Jupiter when it unexpectedly entered into a precautionary status. Data received from NASA’s Juno mission indicates the solar-powered spacecraft went into safe mode twice on April 4 while the spacecraft was flying by Jupiter. Safe mode is a precautionary status that a spacecraft enters when it […]
