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 ...

Dark matter is hypothesized to outweigh "ordinary matter" in the universe by a factor of five. That means all the stuff we ...

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

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 ...

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 ...

In the vast universe, galaxies rotate in ways that don’t make sense if only visible matter is considered. For almost a century, scientists have tried to explain this by searching for a hidden force ...

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

The NASA James Webb Space Telescope captured a stunning image of an Einstein ring, an optical phenomenon created by gravitational lensing. This rare sight, caused by light from a distant galaxy ...

Gravitational lensing—a phenomenon where massive objects bend the light from background galaxies—served as a powerful tool to map the invisible dark matter. Through this technique, the ...

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