LEXINGTON, Ky. (July 12, 2021) — An international team of researchers have discovered a galaxy cluster acting like a passenger on what astronomers are calling an "intergalactic highway."
The cluster is known as the "Northern Clump" and is located about 690 million light years from Earth. Previously, scientists discovered an enormous filament, a thin strip of very hot gas, that stretched for at least 50 million light years. This new study found evidence that the Northern Clump is traveling along this filament, similar to how a car moves along the interstate.
A variety of telescopic images allowed the researchers to observe the galaxy cluster and its movement. Yuanyuan Su, an assistant professor in the University of
