Just two of many extraordinary images taken from the Cassini spacecraft. I have added a red arrow to the first image to point to a tiny speck - our own planet Earth.

It's mind-boggling to think that these images were transmitted successfully to several infinitely more tiny dishes on that tiny speck, taking up to 90 minutes at the speed of light to get there, and that we (tinier still) are somewhere on that tiny speck looking at them... and that some of us, working together, were capable of this great achievement.

In this really interesting slide show, Carl Murray, a member of the Cassini Imaging Team from Queen Mary College London, takes us on a tour of Saturn, its arcs and moons - including Titan, which appears to have geological features similar to Earth's.
