A stark black silhouette races across Jupiter’s swirling clouds — the shadow of volcanic moon Io, sweeping over the giant planet at 17 kilometers per second. In this view, the smallest features resolved on both Io and Jupiter are just 150 kilometers (93 miles) across. Credit: J. Spencer (Lowell Observatory) / NASA / ESA
