This composite image of M82 shows Chandra data (blue), optical data from Hubble (green and orange), and infrared data from Spitzer (red). The pullout is a Chandra image that shows the central region of the galaxy and contains two bright X-ray sources that may be intermediate-mass black holes. Evidence suggests these black holes avoided falling into the center of the galaxy and could be examples of the seeds required for the growth of supermassive black holes in galaxies.
