A newly-detected spinning galaxy filament is reshaping our understanding of cosmic structure, gas flows, and the origins of galactic spin.

The largest known structure in the Universe may be even larger than the large we thought it was. A re-examination of the distribution of powerful space explosions suggests that the Hercules-Corona ...

Astronomers have identified what could be the largest structure ever observed in the known universe—a vast network of galaxy clusters and superclusters containing an astonishing 200 quadrillion solar ...

FLAMINGO simulation maps the universe but reveals a puzzling mismatch: galaxies cluster less than theory predicts.

Astronomers following interstellar comet 3I/ATLAS say its buzz has been eclipsed by a much stranger sight: a colossal, ...

For years, we’ve believed that the universe is a vast, uniform expanse, with the same properties stretching across the cosmos ...

An international team of researchers says it has spotted the largest rotating structure of dark matter and gas-rich galaxies.

The universe is peppered with galaxies, which, on large scales, exhibit a filamentary pattern, referred to as the cosmic web. This heterogeneous distribution of cosmic material is in some ways like ...

A team of researchers led by the University of Arizona recently used NASA’s James Webb Space Telescope (JWST) to examine a group of 10 galaxies that existed only 830 million years after the Big Bang, ...

As the universe evolves, scientists expect large cosmic structures to grow at a certain rate: dense regions such as galaxy clusters would grow denser, while the void of space would grow emptier. As ...
