I've shared the video here because I think this is an incredible video. The visuals that we are getting back from the space program lately are incredible. And now that they are taking photos in a time-lapsed fashion, stitching them together and sharing them in HD video format - we're able to see celestial events in ways no other age of mankind has been able to. This is a trend NASA has set over nearly the last half-century.
Here is the description of the video from the HubbleSite Web site:
"This movie shows Ganymede, Jupiter's largest moon, as it ducks behind the giant planet. Astronomers combined a series of images taken with the Wide Field Planetary Camera 2 aboard NASA's Hubble Space Telescope to make the 18-second movie. The 540 movie frames were created from Hubble images taken over a two-hour period on April 9, 2007."
