An astronomer at the University of Hawaiʻi at Hilo is using data from the Canada–France–Hawaiʻi Telescope (CFHT) on Maunakea ...

Astronomers have long argued that dark matter is the invisible scaffolding that holds galaxies together. Without its immense gravitational pull, the rotational spins of galaxies would force them to ...

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 ...

An international team of astronomers, led by Weichen Wang of the University of Milan, Italy, discovered a massive and unusually quiescent galaxy, aptly named the “Red Potato.” Observed with the ...

How fast can a galaxy build ordered magnetic fields spanning thousands of light-years? Existing theories say several billion ...

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 ...

Protogalaxies as seen by the James Webb Space Telescope (NASA via Courthouse News). (CN) — When astronomers started looking at new images of the deep universe obtained from the James Webb Space ...

The Virgo Cluster holds literally thousands of galaxies, many of which are big, bright, and beautiful. NGC 4535 checks two of ...

T he 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 ...

Astronomers have spotted the most distant and brightest "space laser" ever seen, blasting out from a distant galaxy collision ...

The formation of galaxies in the universe should follow a fairly simple path. It starts with small galaxies, which then grow bigger and bigger until they become the giant galaxies we see in the modern ...

From your place inside the Milky Way, you are living within a galaxy that keeps a detailed chemical diary. Every star holds clues about when it formed and what the galaxy was like at the time. Over ...
