(NASA/IoA/A.Fabian et al.) Chandra's image of the core of the Perseus galaxy cluster shows hot gas in and around the supergiant galaxy, Perseus A. The small dark patch (located at two o'clock from the center of the image) is due to the absorption of X rays by gas in a galaxy of about 20 billion stars that is falling into the central galaxy.
