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.

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 ...

invisible clouds of dark matter in the foreground-a phenomenon known as gravitational lensing. Scientists have a few ideas for what dark matter might be. One leading hypothesis is that dark matter ...

T he Perseus cluster is enormous. It has a mass equivalent to 600 trillion Suns, and it looks like it has not stopped growing ...

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 ...

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

and these wells are created by the gravitational influence of dark matter clumps. As mass gathers in those wells, stars are formed. This continuously "grows" a galaxy and, after millions of years ...

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 ...
