This image shows the Perseus galaxy cluster – one of the most massive known objects in the Universe – in X-ray and optical light, as seen by XMM-Newton's European Photon Imaging Camera (EPIC) and the Digitzed Sky Survey II, respectively.

Using XMM-Newton to study Perseus, astronomers spotted the first signs of this hot gas splashing and sloshing around – a behaviour that, while predicted, had never been seen before.
