“One of the most exciting aspects of the discovery is the new questions it poses,” said study leader Philipp Kronberg of Los Alamos National Laboratories in New Mexico. “For example, what kind of mechanism could create a cloud of such enormous dimensions that does not coincide with any single galaxy or galaxy cluster? Is that same mechanism connected to the mysterious source of ultra high energy cosmic rays that come from beyond our galaxy?”
The plasma cloud is located about 300 million light years away near the Coma Cluster and is spread across a vast region of space thought to contain several galaxies with supermassive black holes, or active galactic nuclei, embedded at their centers.
"One reasonable interpretation is that the cloud represents the aggregate release of magnetic and cosmic ray energy from this grouping of galaxies, which is unusually concentrated," Kronberg told SPACE.com.
Scientists discover 6 million light year wide gas cloud
