Astronomers Witness Extremely Powerful Black Hole Outburst in Distant Galaxy Cluster

Giant cavities in the X-ray emitting intracluster medium (shown in blue, as observed by NASA’s Chandra X-ray Observatory) have been carved out by a black hole outburst. X-ray data are overlaid on top of optical data from the NASA/ESA Hubble Space Telescope (in red/orange), where the central galaxy that is likely hosting the culprit supermassive black hole is also visible.

Astronomers using NASA’s Chandra X-ray Observatory have spotted an unusual outburst activity in the center of SPT-CLJ0528-5300 (SPT-0528 for short), a galaxy cluster located approximately 6.7 billion light-years away. Giant cavities in the X-ray emitting intracluster medium (shown in blue, as observed by NASA’s Chandra X-ray Observatory) have been carved out by a black hole outburst. X-ray data are overlaid on top of optical data from the NASA/ESA...

This Hubble image shows ESO 021-G004, a spiral galaxy located approximately 130 million light-years away in the constellation Chamaeleon. The color image was made from separate exposures taken in the visible and infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). Two filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.
