Scientists Surprised by Relentless Cosmic Cold Front

Perseus Cluster

A gigantic and resilient "cold front" is hurtling through the Perseus galaxy cluster according to data from Chandra & other X-ray observatories. This cosmic weather system spans about two million light years and has been traveling for over 5 billion years, longer than the existence of our Solar System. This image shows the cold front in the Perseus cluster where X-ray data from Chandra – for regions close to the center of the cluster – have been combined with data from the XMM-Newton and ROSAT satellites for regions farther out. The Chandra data have been specially processed to brighten the contrast of edges to make subtle details more obvious.
