This image of NGC 4151 shows a close-up of the central region of the galaxy in an inset. The dimensions of the inset are only 2,000 light-years across. Here, the Chandra X-ray data from the larger image are shown in blue, and we add in radio data from the VLA (purple) and HST data (yellow) showing oxygen emission. The linear structures show clear evidence for an earlier outburst from a supermassive black hole at the center of the galaxy.
