A composite image of the Perseus galaxy cluster. Visible and radio light are shown in red, while X-ray light from the Chandra Observatory is shown in blue. The unusual X-ray emissions, particularly a 3.5 keV signal, hint at the possible existence of fluorescent dark matter. The central region shows a deficiency in 3.5 keV X-rays, while outer regions exhibit an excess.
