A recent study from an international team of astronomers has uncovered an unexpected source of diffuse radio emission coming from a massive galaxy cluster. The cluster known as Abell 2256, located about 650 million light years away from Earth, contains a wide variety of galaxies and hot gas, making it one of the most complex and interesting systems to observe. What was unexpected was the observation of a diffuse radio emission coming from the cluster, which scientists believe is caused by the turbulent motion of the hot gas in the cluster. This is the first time such emission has been observed in a galaxy cluster, and has implications for our understanding of the physical processes of galaxy clusters.
