Chandra X-ray Image of M84
This image of M84 shows X-ray data from the Chandra X-ray Observatory. A number of bubbles generated from the supermassive black hole at the center of this giant galaxy are visible in this image. The particles that create these bubbles travel outward from the black hole in the form of a two-sided jet. Smaller bubbles are found within larger ones, and this nesting provides clear evidence for repeated outbursts from the central black hole.
