10 years of [XMM] Newton and the hexagon on Saturn

The European Space Agency is marking the 10th anniversary of the launch of the X-ray observatory XMM-Newton with a less than informative slide-show. Of better value, if un-embeddable, is the BBC hosted version. Meanwhile Nasa’s Cassini probe, after imaging Saturn’s northern lights, has been capturing visible-light images of the mysterious hexagon-shaped jet-stream around Saturn’s north pole – full image here. First seen by the Voyager probes in 1979, infrared images of the structure were previously captured in 2006. Image Credit: NASA/JPL/University of Arizona.
