Researchers have found a galaxy cluster acting like a passenger on what astronomers are calling an "intergalactic highway." The cluster is known as the "Northern Clump" and it 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. A new study found evidence that the Northern Clump is traveling along this filament, similar to how a car moves along the interstate.
