On Monday, the NASA/ESA Cassini spaceprobe flew just 30 miles (50km) over the surface of Enceladus, and at a staggering 40,000mph! Cassini took numerous images of the grooves that run along the moon's south pole, where jets of icy water vapour erupt hundreds of miles into space.
To see the latest images, take a look at the Cassini flyby of Enceladus internet page, including the image below. For the thoughts of the Cassini scientists, see the Cassini blog.
