The Phoenix Cluster is galaxy cluster in which large groups of galaxies, gas, and dark matter all come together and are held by gravity.
In this particular galaxy cluster, new discoveries are being made using the Hubble telescope, and two other observatories owned by NASA. The new data on the Phoenix Cluster reveals small filaments of gas and dust from the center where stars are forming. These filaments stretch longer than the Milky Galaxy, which are the longest ever seen in a galaxy cluster.
In most galaxies, black holes are classified by their behavior. However, there is a central black hole in the Phoenix Cluster which shares both properties of quasars, which are super bright objects that are fueled by black holes, and radio galaxies, which contain particles that glow in radio waves. This particular black hole is suggested to be flipping between these two properties.
These properties of the Phoenix Cluster in unusual circumstances provides insight on how black holes also evolve in their environments and help us understand the processes of how stars, galaxies, and even black holes are formed.
