This map of our galaxy shows all the objects that were detected in the XMM-Newton slew survey, one of which was the nova V598 Puppis. The plot is colour-coded such that sources of a lower energy are red and those with a higher energy are blue. Also, the brighter the source, the larger it appears on the map. The plot is in galactic coordinates (the centre of the plot corresponds to the centre of the Milky Way). Credit: ESA/XMM-Newton/EPIC (R. Saxton et al.)
