Jupiter’s volcano-laden moon captured in photos from NASA’s Juno mission

NASA released some captivating shots of Io, one of Jupiter’s four Galilean moons, from the Juno space probe. The spacecraft came within 930 miles of the moon’s surface on Saturday.

Io has roughly 400 active volcanoes and is the most volcanically active known body in the solar system. Scientific American noted that the volcanoes look like “dark pits” in the new images.
