Astronomers speak of the cosmic web as the most fundamental, large-scale structure of our universe. They picture it as a network of filaments and voids – spanning untold billions of light-years – ...

Using data from the Keck Cosmic Web Imager, an animation has been created that "reveals a 3-D slice through a network of hydrogen gas filaments that crisscross the spaces between galaxies," according ...

New data reveals a 3-million-light-year filament connecting two galaxies, each of which hosts a supermassive black hole. Reading time 3 minutes Researchers compiled hundreds of astronomical ...

ESA’s XMM-Newton X-ray observatory has revealed three massive filaments of hot gas flowing towards a cluster of galaxies, uncovering a portion of the cosmic skeleton that pervades the entire Universe.

Like rivers feeding oceans, streams of gas nourish galaxies throughout the cosmos. But these streams, which make up a part of the so-called cosmic web, are very faint and hard to see. While ...

Long before galaxies sparkled in the sky or stars took shape, invisible forces stirred in the early Universe. One of those forces—magnetism—emerged in ways scientists are only now beginning to ...

An international team led by the University of Oxford has identified one of the largest rotating structures ever reported: a "razor-thin" string of galaxies embedded in a giant spinning cosmic ...

Add Yahoo as a preferred source to see more of our stories on Google. Dark matter in the Coma Cluster. Dark matter represented by green clouds over the Coma Cluster and distant galaxies as seen by ...

The JWST COSMOS-Web result, published in The Astrophysical Journal on May 6, 2026, traced the cosmic web by cataloguing 164,000 galaxies and placing them within the large-scale structure across cosmic ...

Galaxies can collect in large filamentary structures that have—until now—been considered rigid. A new study suggests one filament may be rotating. Illustration of the rotation of neutral hydrogen ...
