Jupiter’s moon Io is the most volcanically active body in our solar system, so it’s not a shock that astronomers captured several eruptions while their telescopes were trained on the satellite. However, the three eruptions were uncommonly massive (among the 10 largest seen there) and occurred within the span of a couple of weeks—eruptions of this class are only thought to occur every other year, on average. Researchers may be able to glean enough from these images to help us get to the bottom of a couple of Ionian mysteries.
