NASA Juno Probe Reveals Subsurface Heat Data from Jupiter's Volcanic Moon Io

·1 views

NASA's Juno spacecraft has recorded the first-ever temperature measurements beneath the surface of Io, Jupiter's most volcanically active moon. The data was gathered during two close flybys of the moon. Findings indicate significant heat buildup within Io's shallow subsurface layers. The measurements also reveal that most of Io's surface is unusually smooth in composition. The discoveries offer new insights into the internal workings of the most volcanically active body in the solar system.

NASA Astronaut Williams, Two Cosmonauts to Return After 241 Days on ISS

NASA astronaut Chris Williams and Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergei Mikaev are set to conclude their 241-day mission aboard the International Space Station. The crew will depart the orbiting laboratory aboard the Soyuz MS-28 spacecraft, undocking from the Rassvet module at 3:02 a.m. EDT on Sunday, July 26. A parachute-assisted landing is scheduled for 6:26 a.m. EDT following the undocking. The trio has spent roughly eight months conducting research and operations on the ISS before making their return to Earth.

NASA's Chandra Observatory Reveals New X-ray View of Galaxy Messier 94

NASA's Chandra X-ray Observatory released a fresh look at the spiral galaxy NGC 4736, commonly known as Messier 94, on June 30, 2026. The galaxy is notable for its bright inner starburst ring, a region where new stars are actively forming. Scientists believe this star formation may be driven by gas channeled inward through the galaxy's distinctive oval-shaped structure. The new imagery offers deeper insight into the physical processes shaping this well-studied spiral galaxy.

NASA's Juno Maps Subsurface Heat Across Jupiter's Volcanic Moon Io

NASA's Juno spacecraft used its Microwave Radiometer instrument to map thermal activity beneath the surface of Jupiter's moon Io during two close flybys. The first pass, known as Perijove 57, took place on December 30, 2023, focusing primarily on Io's northern hemisphere. A second flyby, Perijove 58, followed shortly after and extended coverage to additional regions of the moon. Together, the two flybys produced overlapping footprint data that allow scientists to study heat distribution hidden below Io's surface. The findings aim to deepen understanding of the intense volcanic and thermal processes that make Io one of the most geologically active bodies in the solar system.

NASA's Juno Spacecraft Maps Heat Rising Below Jupiter Moon Io's Surface

NASA's Juno spacecraft has captured data revealing heat emanating from beneath the surface of Io, one of Jupiter's moons. The findings come from the Microwave Radiometer (MWR) instrument onboard the probe, which was used to generate a detailed heat map of the moon. Unlike infrared instruments that only measure surface temperature, the MWR's lowest frequency microwave channels — operating at 0.6 and 1.25 gigahertz — can penetrate several meters below Io's surface. This capability allows scientists to study subsurface thermal activity on the volcanic moon in a way that surface-level observations cannot. The data offers new insight into the internal heat processes driving Io's intense geological activity.
