Astronomers tracking interstellar comet 3I/ATLAS reveal a far bigger story: a colossal, rotating chain of galaxies that may ...

The shape of the universe is not something we often think about. My colleagues and I have published a new study that suggests ...

But there are several important anomalies, including a widely debated one called the Hubble tension. It is named after Edwin ...

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

The simulation hypothesis—the idea that our universe might be an artificial construct running on some advanced alien computer ...

Another batch of the ‘impossible’ galaxies turned out not to be standard galaxies at all, but a new type of object that ...

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

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

By studying tiny distortions in the shapes of distant galaxies, scientists mapped dark matter and dark energy across one of the largest sky surveys ever assembled. Their results back the standard ...

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

By studying faint distortions in galaxy shapes across a vast region of sky, scientists probed the hidden structure of the universe. In the standard picture of the universe, nearly everything is hidden ...

Ramanujan’s elegant formulas for calculating pi, developed more than a century ago, have unexpectedly resurfaced at the heart ...
