The third day of the 18th annual Space Telescope Advent Calendar features a deep-space image of more than 100 galaxies close ...

Scientists have observed the largest-known rotating structure in the cosmos - a gargantuan thread-like assemblage of hundreds ...

Galaxy clusters are often described by superlatives. After all, they are huge conglomerations of galaxies, hot gas, and dark matter and represent the largest structures in the Universe held together ...

Astronomers have discovered a previously hidden "cosmic fuel tank" in an infant cluster of forming galaxies. This vast reservoir of cool molecular gas is found in the protocluster known as SPT2349-56, ...

Only one billion years after the Big Bang, clusters of galaxies were already forming. This discovery pushes back the age of the youngest known galaxy cluster by a third, and shows that the largest ...

Does dark matter interact with itself? The answer may lie in vast clusters of colliding galaxies. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

Cosmology scientists at the Lawrence Berkeley National Laboratory have made a rare discovery: a cluster of galaxies that span most of the observable universe. This cluster — the Carousel Lens — is ...

When studying local galaxy cluster Abell 3667, Anthony Englert GS, a Ph.D. candidate in physics, noticed something unique. Connecting the brightest galaxies in two small clusters within Abell 3667 was ...

The history of how stars and galaxies came to be and evolved into the present day remains among the most challenging astrophysical questions to solve yet, but new research brings us closer to ...

(Phys.org)—Most galaxies lie in clusters, groupings of several to many thousands of galaxies. Our Milky Way galaxy itself is a member of the "Local Group," a band of about fifty galaxies whose other ...
