Astronomers Find Enormous Wave of Hot Gas Rolling through Nearby Galaxy Cluster
May 2, 2017 by News Staff / Source
A wave spanning 200,000 light-years (about twice the size of our Milky Way Galaxy) is rolling through the Perseus Cluster, according to observations from NASA’s Chandra X-ray Observatory coupled with radio observations and computer simulations.
Galaxy clusters are the largest structures bound by gravity in the Universe today.
Approximately 11 million light-years across and located 240 million light-years away, the Perseus Cluster (Abell 426) is named for its host constellation.
