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 ...

A UC Davis graduate student who is leading a study of the collision of galaxy clusters 5 billion light years away will discuss the team’s findings today, Jan. 10, in a press briefing at the annual ...

Astronomers have employed the upgraded Giant Metrewave Radio Telescope (uGMRT) and the MeerKAT radio telescope to observe a ...

Astronomers have successfully charted a colossal cluster of galaxies, extending billions of light years. This unprecedented exploration into cosmic structures could provide new insights into the ...

When two pairs of galaxy clusters collide, the final result is not four separate objects, but one giant galaxy cluster. Astronomers using data from NASA's Chandra X-ray Observatory and several other ...

Scientists have detected a surprisingly hot galaxy cluster dating back to the universe’s infancy. The cluster formed far earlier and burned far hotter than current models predict. Researchers believe ...

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 ...
