Volcanic Eruptions on Jupiter's Moon Io Tracked Over Time

Io is the most volcanically active body in the solar system. Using two of the world's largest telescopes, the 10-meter Keck II and 8-meter Gemini North, both located in Hawaii near the summit of Mauna Kea, astronomers from the University of California, Berkeley, tracked 48 volcanic hotspots over more than two years, from 2013 through 2015. This high-resolution image of the volcanic regions Loki Patera and Amaterasu Patera on Jupiter's moon Io was captured from Earth using adaptive optics observa
