  NASA’s Juno Spacecraft Detects Callisto’s Aurora, Completing Jupiter’s Galilean Moons Set

  NASA’s Juno spacecraft has captured Callisto’s elusive auroral footprint, completing the “family portrait” of Jupiter’s Galilean moons. Each moon carves its own aurora into the gas giant’s poles, revealing how they interact with Jupiter’s powerful magnetosphere. Callisto’s faint arc appeared during a 2019 flyby, finally confirming i...

  NASA Engineers Rescue JunoCam with Deep-Space Heating Hack

  NASA’s JunoCam, once believed nearly lost to Jupiter’s intense radiation, has made a stunning comeback thanks to a bold experiment. Engineers used a process called annealing—heating the camera from afar—to reverse internal damage and restore image clarity. Just in time for a close flyby of the volcanic moon Io, the camera delivered detailed...

  NASA's Juno Detects Io's Most Powerful Volcanic Eruption Yet

  NASA’s Juno spacecraft has recorded the most powerful volcanic eruption on Io, Jupiter’s most volcanic moon. The eruption site, detected on 27 December 2024, is fueled by a massive magma chamber spanning 105,000 square kilometers. The heat energy released is estimated at 80 trillion watts, exceeding Earth’s total power output. The volcanic ac...

  Jupiter’s Moon Io Shows No Magma Ocean as New Findings Explain Volcanic Eruptions

  NASA's latest findings indicate that Jupiter's volcanic moon Io does not have a global magma ocean beneath its surface, debunking previous theories. This conclusion comes from analysis of data from NASA's Juno spacecraft and archival observations from the Galileo mission. The study suggests that Io's interior is more solid than expected, with volca...
