European astronomers have used the Atacama Large Millimeter Array (ALMA) and the James Webb Space Telescope (JWST) to observe ...

How far the Milky Way's disc extends has long been difficult to define — it doesn't end sharply, but fades away gradually at its outer edges. Now, for the first time, an international team of ...

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 ...

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 ...

Our universe is full of mysteries, but few are as perplexing as the dark, tiny galaxies that hover around larger ones like ...

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 ...

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 ...

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 ...
