A study of the fascinating galaxy system nicknamed "The Stingray" suggests that mysterious little red dots could be a phase ...

The first time I heard about galaxies without dark matter, I was sitting in my very first graduate class at the University of São Paulo. It was 2018, and the discovery had just been announced. A team ...

These halos, crucial to understanding galaxy formation, were largely unknown until the Hobby-Eberly Telescope Dark Energy ...

Although magnetic forces are usually much weaker than gravity in shaping cosmic structures, the findings suggest that strong, ordered magnetic fields may have emerged earlier than expected. Over time, ...

Published in a new study available in pre-print on arXiv, this discovery of NGC 1052-DF9 adds significant weight to the ...

A blazing supermassive black hole can influence far more than its own galaxy. Scientists found that quasars emit radiation strong enough to shut down star formation in nearby galaxies millions of ...

In the vast darkness of the early universe, a spiral of light named Zhúlóng offers a new glimpse into cosmic history. This galaxy, shaped like our Milky Way, formed just a billion years after the Big ...

For the first time, scientists have reconstructed the full history of a galaxy outside the Milky Way using chemical clues. By analyzing oxygen across NGC 1365 and comparing it with simulations, they ...

Astronomers have long argued that dark matter is the invisible scaffolding that holds galaxies together. Without its immense ...

The study of galaxies and their star formation processes remains a cornerstone of modern astrophysics. Galaxies are the fundamental building blocks of the Universe, each hosting a complex interplay of ...

Abstract : Weighing in at 1042 kilograms and measuring 1021 meters across, galaxies are perhaps the most awe-inspiring objects known to mankind. They are also the only places in an otherwise dark and ...
