These images show two of the galaxy clusters in the study, the Perseus Cluster and the Centaurus Cluster. Chandra data represented in blue reveal X-rays from filaments of hot gas, and VLT data show cooler filaments in red.

Betelgeuse’s Mysterious Dimming Likely Caused by Huge Outburst

Aug 13, 2020 by News Staff

The red supergiant Betelgeuse is one of the brightest stars in the night sky and appears even more luminous because it is so close to Earth, only 650 light-years...

Evidence for the biggest black hole eruption seen in the Universe comes from a combination of X-ray data from Chandra and XMM-Newton, and the Murchison Widefield Array and Giant Metrewave Telescope, as shown here. The eruption is generated by a black hole located in the central galaxy of the Ophiuchus galaxy cluster, which has blasted out jets and carved a large cavity in the surrounding hot gas.

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.
