That’s exactly what happened on March 28, 2004, when the Hubble Space Telescope imaged three of Jupiter’s moons eclipsing the sun. A series of images taken at different near-infrared wavelengths show the shadows of Io, Ganymede and Callisto traveling across Jupiter’s mighty disk. These moons make up three of the four Jovian moons discovered by Galileo in the early 1600s. The fourth moon, Europa, was located on the opposite side of the planet at the time of the observation.
