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

Magnetic fields that stretch across thousands of light-years should take a very long time to organize. Standard dynamo theory ...

Astronomers have detected ordered magnetic fields in galaxies so young that conventional models struggle to explain how those ...

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. A team had found a small, strange galaxy that appeared to ...

An international team led by the University of Geneva (UNIGE) has identified three ultra-massive galaxies—nearly as massive as the Milky Way—already in place within the first billion years after the ...

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 ...

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 ...

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 ...

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 ...

(Nanowerk News) An international team that was led by the University of Geneva (UNIGE) and includes Professor Stijn Wuyts from the University of Bath in the UK has identified three ultra-massive ...

Astronomers have used the James Webb Space Telescope to peer inside the heart of spiral galaxies, where young stars carve out glowing paths. The space observatory, named after a North Carolina native, ...

GRB 230906A, a short gamma-ray burst first detected in 2023, points to a faint galaxy embedded within a long stream of torn ...
