Text, Beating heart of the Centaurus galaxy cluster. Centaurus constellation.
Hot gas fills the spaces between galaxies in the Centaurus galaxy cluster, emitting x rays seen by NASA's Chandra X Ray Observatory.
Cavities in the X ray emitting gas cloud match up with radio emissions detected by the ground based Jansky Very Large Array.
The radio waves come from high energy particle jets powered by the black hole. The jets appear to occur intermittently every 5 to 10 million years, dispersing element rich gas out into the cluster like a very slowly beating heart.
The cavities that formed the most recently are located nearest to the black hole. The high energy heartbeats also keep the hot gas from cooling enough to form large numbers of stars.
Studying the Centaurus cluster in multiple wavelengths reveals a dynamic environment with a cosmic heartbeat at its center.
