PICK OF THE WEEK: Secrets of shiniest moon revealed

The latest findings from the Cassini Huygens mission to Saturn have thrown up some fascinating facts about the shiniest object in the solar system. Enceladus is one of the planet’s moons and was previously thought to have been cold and still. But a fly-by of the tiny moon, just 100 miles above its surface, revealed it to have active ice volcanoes. Scientists also discovered that it is just 314 miles across - small enough to fit into the length of the UK. The fly-by was also able to work out that Enceladus shoots jets of ice and water vapour from its south pole. There are cracks in the moon’s surface - which look like crevases on Earth - which scientists have nicknamed “tiger stripes”.
