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 ...

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 ...

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 ...

"WIMPs are still the leading candidate for dark matter, but billions of dollars of experiments have been done, only getting ...

A newly revealed cosmic image shows two galaxy clusters colliding as one. Nicknamed the Champagne Cluster, it offers rare clues about dark matter behaviour and an unfinished celestial crash.

NASA’s flagship X-ray observatory is starting the calendar with a flourish, unveiling a richly detailed view of a distant system nicknamed the Champagne Cluster. The new composite image captures a ...

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 ...
