Hubble captures transit of Saturn's moons

The Hubble telescope has taken some very nice pictures of four of Saturn's moons transiting at once.



Titan is the largest visible at the top. Enceladus, Dione, and their shadows on Saturn are on the left, while Mimas is visible on the right. The moons, Saturn and Earth with the Hubble telescope orbiting it have to be aligned just right to get these images. Someone had to do the calculations of place and time so that Hubble could be pointed at Saturn to catch it.

More pictures and videos are available at the HubbleSite.
