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

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

Two galaxies are merging in the deep cosmos. And the James Webb Space Telescope just captured a vivid view of the scene. The interacting galaxies, called Arp 107, collided hundreds of millions of ...

Why do some galaxies spin like giant tops, while others appear stationary? This question has puzzled astronomers for decades, ...

Astronomers combined images from the James Webb Space Telescope and Hubble Space Telescope to create the highest-resolution image of two galaxies, IC 2163 on left and NGC 2207, on the verge of merging ...

An international team led by the University of Oxford has identified one of the largest rotating structures ever reported: a ...

The standard model for how galaxies formed in the early universe predicted that the James Webb Space Telescope (JWST) would see dim signals from small, primitive galaxies. But data are not confirming ...

Despite appearing "dead"—i.e., forming no new stars—some red galaxies may secretly be alive, quietly birthing small stars under our noses. This is the conclusion of astronomy professor Charles ...
