Juno uncovers Io's buried heat, hinting at lava flows or rapid subsurface conduction

NASA’s Juno spacecraft, using its Microwave Radiometer, measured Io’s subsurface temperatures for the first time and found a sharp, 40+ degree Fahrenheit rise within feet of the surface. The results from two close flybys (2023–2024) suggest heat moving through Io’s crust by conduction or stemming from buried lava flows, offering a new way to study tidal heating and heat transport on rocky worlds and potentially informing heat dynamics on other moons.

Io Unleashes Solar System’s Most Powerful Volcanic Outburst, NASA Finds

NASA’s Juno spacecraft detected the solar system’s most energetic eruption on Io—a 40,000-square-mile hotspot in the moon’s southern hemisphere emitting well over 80 trillion watts from multiple simultaneous sources, suggesting a vast interconnected magma system; observed by JIRAM during the December 27, 2024 flyby with visible surface changes near Io’s south pole, and researchers plan a March 3 flyby recheck.

Juno Mission Challenges Understanding of Io's Volcanic Activity

NASA's Juno mission has revealed that the volcanoes on Jupiter's moon Io are powered by individual magma chambers rather than a global magma ocean, solving a long-standing mystery about Io's volcanic activity. This discovery, based on data from Juno's close flybys, suggests that tidal flexing from Jupiter's gravitational pull generates internal heat, melting parts of Io's interior. The findings have broader implications for understanding other celestial bodies, including moons like Enceladus and Europa, as well as exoplanets.

December Stargazing: Jupiter Shines Brightest in the Night Sky

Jupiter, the largest planet in our solar system, is easily observable from Earth and is known for its massive size and bright appearance. With a diameter that can fit 11 Earths and a mass greater than all other planets combined, Jupiter's gravitational influence shapes the orbits of many comets and asteroids. Its four largest moons, discovered by Galileo, can be seen with modest telescopes. NASA's Juno mission, which began in 2016, has provided significant insights into Jupiter's interior and its moons, with future missions like the Europa Clipper set to expand our understanding further.

NASA's Juno Reveals Stunning New Images of Jupiter's Beauty and Storms

NASA's Juno spacecraft completed its 66th close flyby of Jupiter, capturing raw data and images that are processed by citizen scientists to reveal the planet's atmospheric phenomena. These images, while artistically enhanced, provide valuable insights into Jupiter's weather and structure. The mission, extended beyond its original 2017 end date, will continue until September 2025, offering more opportunities to study Jupiter before the spacecraft is intentionally crashed into the planet.

"Europa's Oxygen Production Could Sustain 1M Humans: NASA"

NASA's Juno mission has found that Jupiter's moon Europa produces 1,000 tons of oxygen every 24 hours, enough to support a million people for a day, but much less than previously thought. This new data may narrow the odds of Europa supporting life in its vast underground ocean, with ongoing missions like Clipper aiming to determine its habitability. The oxygen production on Europa is a result of Jupiter's radiation interacting with frozen water ice on the moon's surface, but it's still unclear how much of it reaches the underground ocean.

"NASA's Juno Mission Reveals Oxygen Levels on Europa, Impact on Habitability"

NASA's Juno mission to Jupiter has measured the rate of oxygen production at the Jovian moon Europa to be around 26 pounds every second, substantially less than previous estimates. The findings, published in Nature Astronomy, were derived from data collected by the spacecraft's Jovian Auroral Distributions Experiment (JADE) instrument. Europa's icy surface is bombarded by charged particles from Jupiter, which split water molecules to generate oxygen, potentially providing a source of metabolic energy for the moon's subsurface ocean. The mission's next target is the volcano-festooned moon Io, with upcoming flybys to gather more data.

"Comparing NASA's Voyager Jupiter Flyby Footage to Modern Planet Photos"

NASA's Voyager 1 spacecraft flew past Jupiter 45 years ago, capturing iconic footage of the gas giant. Comparing the images from Voyager to those captured by NASA's Juno mission today reveals a significant difference in detail and clarity. Juno's modern technology and image processing have provided stunningly detailed, colorful snapshots of Jupiter and its moons, showcasing intricate features and violent weather patterns. The Voyager spacecrafts are now in interstellar space, while Juno continues to orbit Jupiter and send back images until at least September 2025.
