The Hubble space telescope came through big time in January, when it captured a string of images showing three of Jupiter's largest moons — Europa, Callisto, and Io — passing in front of the planet's face at the same time.
Jupiter has more moons —67— than any other planet in our solar system, The Washington Post notes, but seeing three of the moons passing in front of the planet's banded face at the same time is a serious rarity. The Hubble Heritage Team reports that such an event only takes place once or twice in a decade.
Hubble made the series of images over about 40 minutes — you can watch a cool time-lapse of the event in the video, below. —Sarah Eberspacher
