In these simulations, the researchers began with a massive primordial black hole seed of about 50 million times the Sun’s mass, then followed how gas flowed into it, how stars formed nearby, and how ...

Astronomers combined data from NASA’s JWST and Chandra X-ray Observatory to create a stunning new image of two merging spiral ...

A recent study published on arXiv has revealed a black hole so massive and so ancient that it challenges long-standing models ...

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: ...

Distance records are an excellent proxy for the state of the art in astronomy. Finding extremely faraway galaxies is hard. In ...

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

Scientists have discovered a giant cosmic filament where galaxies spin in sync with the structure that holds them together.

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 ...

The FLAMINGO super simulation maps the universe from its earliest moments but finds galaxies cluster less than cosmological ...

Contrary to popular belief, our universe may not be constantly expanding after all. A groundbreaking study by South Korean ...

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 ...
