Jupiter’s Volcanic Moon Io

NASA’s Juno mission captured this infrared view of Jupiter’s volcanic moon Io, when the spacecraft was about 50,000 miles (80,000 kilometers) away.

This infrared image was derived from data collected by the Jovian Infrared Auroral Mapper (JIRAM) instrument aboard Juno. In this image, the brighter the color the higher the temperature recorded by JIRAM.
