Understanding how galaxies grow has long stood as one of astronomy’s core challenges. Over time, scientists have gathered ...

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 ...

If not in visible stars and galaxies, the most likely hiding place for the matter is in the dark space between galaxies.

Two barred spiral galaxies, known as NGC 7733 and NGC 7734, are in the process of merging. The lower galaxy has a dusty knot atop its upper arm, which marks a third galactic companion. | Credit: ...

Scientists have observed the largest-known rotating structure in the cosmos – a gargantuan thread-like assemblage of hundreds of galaxies, gas and dark matter that makes up a filament in the ...

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

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 ...

It got called the crisis in cosmology. But now astronomers can explain some surprising recent discoveries. Artist illustration of a black hole surrounded by extremely thick clouds of gas and dust.

Cosmic dawn galaxies seen by JWST reveal hidden clues about dark matter and keep rival theories about its true nature alive.

The universe suddenly looks a lot more crowded, thanks to a deep-sky census assembled from surveys taken by NASA’s Hubble Space Telescope and other observatories. Astronomers came to the surprising ...
