NASA’s Juno Peers Beneath Io’s Surface

NASA's Juno mission has provided unprecedented insights into the interior of Jupiter’s volcanic moon, Io, utilizing data collected by its Microwave Radiometer (MWR). The MWR instrument detected significant heat signatures emanating from directly below Io’s surface, revealing a thermal anomaly. Specifically, measurements at frequencies of 0.6 and 1.25 gigahertz were able to penetrate approximately six to […], allowing scientists to assess subsurface temperatures. This represents a novel approach to studying Io’s composition and geological activity beyond just surface observations. Researchers are now analyzing this detailed temperature map to better understand the processes driving Io’s intense volcanism.
