An image taken by the Hubble Space Telescope reminds us of how powerful this aging scope really is. Magnitudes sharper than the images originally sent by Pioneer as it passed by in the 1970s.
Ganymede from Juno
Some incredibly sharp images from the Juno mission of Ganymede. The first new views of this beautiful moon since Galileo. See more from kevinmgill on flickr. Also see the thread building up to these full composites in unmannedspaceflight.com.
