If you like Saturn, You'll Love This

Here is a snippet:

Hubble catches four moons on the face of Saturn On February 24, 2009, Hubble's Wide Field and Planetary Camera 2 captured a rare quadruple transit: four moons crossed in front of Saturn's disk at the same time. The moons are, from left, white Enceladus and Dione (both of which are near the rings and casting shadows onto the planet); orange Titan; and white Mimas (just at the right-hand edge of the disk). We can only observe such transits from Earth for a brief period once every fifteen years as Earth nears and then crosses Saturn's ring plane.
