XMM-Newton slew survey of the Vela supernova remnant

In its on-going slew survey of the sky, XMM-Newton is able to map with high efficiency very large sky features. Among these, is the 20 000 year-old Vela supernova remnant (right) - occupying a sky area 150 times larger than the full moon. This object is compared here with an image previously taken by the former ROSAT mission (left).
