When studying local galaxy cluster Abell 3667, Anthony Englert GS, a Ph.D. candidate in physics, noticed something unique. Connecting the brightest galaxies in two small clusters within Abell 3667 was ...

The galaxy cluster PLCKG 287.0+32.9, located 5 billion light-years away, exhibits an exceptionally violent collision of three subclusters, characterized by extensive turbulence and shock waves.

Current theories say young galaxy clusters should be relatively cool compared to older ones. But researchers recently found a very young cluster that was shockingly hot. Study author Dazhi Zhou says ...

Astronomers have discovered a ghostly, million-light-year-long bridge of stars connecting two massive galaxies within the Abell 3667 cluster, 700 million light-years away. This glowing thread of ...
