X-ray & Optical Images of SDSS J1354+1327
Using data from several telescopes including Chandra, astronomers have caught a supermassive black hole snacking on gas and "burping" twice. These images show the galaxy, called SDSS J1354+1327 (J1354 for short), in a wide-field image from Hubble. An additional image from the Chandra data is of the central region around the galaxy's supermassive black hole. The combined X-ray and optical data (shown with labels) reveal that the supermassive black hole in J1354 consumed two clumps of stars and gas about 100,000 years apart.
