. A mysterious signal has been seen in X-ray data from a study of over 70 galaxy clusters with Chandra and XMM-Newton. This spike of intensity at a specific wavelength of X-ray light has several intriguing explanations. More data and investigation will be needed to confirm both the signal's existence and nature. This image shows a new view of the Perseus cluster, one of the galaxy clusters included in the new study. X-ray: NASA/CXC/SAO/E.Bulbul, et al.
