Astronomers have made a groundbreaking discovery in the Perseus galaxy cluster, located 240 million light-years from Earth.

The researchers found a huge clump of dark matter about 1.4 million light-years west of the cluster’s center.

The Perseus cluster is a vast collection of thousands of galaxies, all bound together by gravity. Famed for its unbelievable ...

"All the odd shapes and swirling gas observed in the Perseus cluster now make sense," said astronomer James Lee.

An international team of astronomers has solved one of the longstanding cosmic mysteries by uncovering direct evidence of a ...
