"Galaxy clusters are also dominated by dark matter," Jacqueline McCleary, assistant professor of physics at Northeastern University, said in a statement. "Eighty to 90% of their mass is dark ...

Hubble's new image of galaxy cluster Abell 209 reveals over 100 galaxies and gravitational lensing effects from dark matter ...

The James Webb Space Telescope (JWST) has provided groundbreaking insights into the Bullet Cluster, a cosmic collision zone located 3.8 billion light-years from Earth. The JWST’s enhanced imaging ...

Based on their higher-resolution mass map, Coe and his collaborators confirm previous results showing that the core of Abell 1689 is much denser in dark matter than expected for a cluster of its ...

This unprecedented view of the Bullet Cluster provided by the James Webb Space Telescope and the Chandra X-ray Observatory ...

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.

Images 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 … ...

A massive, spacetime-warping cluster of galaxies is the setting of today's NASA/ESA Hubble Space Telescope image. The galaxy ...

Dazzling sky survey maps 5,259 galaxy clusters and sheds light on dark matter The mysterious substance that makes up 26 percent of the mass in the universe played a key role in early galaxy formation.

Euclid aims to figure out how these clusters orbit the rest of the Milky Way, revealing how dark matter is distributed throughout our galaxy. The Horsehead Nebula Euclid's view of the Horsehead ...

Space Galaxy cluster smash-up lets us observe dark matter on its own. Astronomers have spotted two colossal clusters of galaxies colliding and shooting out all of their dark matter, which may ...

Particle accelerators like the Large Hadron Collider have failed to turn up potential dark matter candidates, but could galaxy cluster smashes be used as cosmic dark matter colliders?
