A massive clump of dark matter in the Perseus galaxy cluster is linked to its core by a bridge of dark matter, evidence of a ...

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

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

T he Perseus cluster is enormous. It has a mass equivalent to 600 trillion Suns, and it looks like it has not stopped growing. New evidence suggests that it is undergoing a merging process with ...

The structural backbone of this bridge is dark matter, the universe's most ... This investigation hinged on a phenomenon called "gravitational lensing," first predicted by Albert Einstein in ...

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

NSF–DOE Vera C. Rubin Observatory is gearing up to illuminate the universe’s darkest secrets with groundbreaking new ...

The telescope can map out the location of otherwise-invisible dark matter by looking for signs of gravitational lensing—the phenomenon where the gravity from massive objects distorts the light ...

In its quest to chart the evolution of the universe, ESA’s space telescope has already amassed a massive catalog of galaxies ...
