Hubble Space Telescope Images ‘Hiding’ Ganymede

The orbiting Hubble Space Telescope (HST) snagged this amazing image of the planet Jupiter and it’s largest moon, Ganymede, as the latter was drifting behind the giant planet. Astronomers use images like this to study the upper reaches of Jupiter’s atmosphere. Earth based astronomers will need to wait until spring before they can do much observing of Jupiter as it is now sitting low in the western sky as darkness falls.
