The Bullet Cluster as seen by the James Webb Space Telescope (JWST) consists of a larger cluster of galaxies (left) and a smaller cluster (right). The hot gas seen by the Chandra X-ray Observatory is ...

NASA's James Webb Space Telescope (JWST) has produced a new image of the Bullet Cluster, which is a titanic collision between two individual galaxy clusters. The image, produced in conjunction with ...

Astronomers using observations from the NASA/ESA Hubble Space Telescope and NASA’s Chandra X-ray Observatory have studied how dark matter in clusters of galaxies behaves when the clusters collide. The ...

Astronomers have untangled a messy collision between two massive clusters of galaxies in which the clusters' vast clouds of dark matter have decoupled from the so-called normal matter. Astronomers ...

In 2006, scientists observed the Bullet Cluster and discovered some of the best direct evidence for dark matter. This galaxy cluster, formally known as 1E 0657-56, was created when two large galaxy ...

A team of astronomers used the Hubble Space Telescope to find the best evidence yet for the existence of dark matter, present in the form of a ghostly ring in a galaxy cluster. The ring had formed ...

For astronomers studying dark matter, the Bullet Cluster is one of the greatest laboratories in the universe. It was discovered almost by accident, a blip of x-rays in the sky that was detected by ...

This artist's concept shows what happened when two massive clusters of galaxies, collectively known as MACS J0018.5, collided: The dark matter in the galaxy clusters (blue) sailed ahead of the ...
