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

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 ...

Astronomers have detected ordered magnetic fields in galaxies so young that conventional models struggle to explain how those fields formed so fast. Observations from the Atacama Large ...

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

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 ...

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 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 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 ...

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, ...

(Nanowerk News) An international team of researchers including The University of Tokyo Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU, WPI) has found evidence showing that ...

The research could shed light on how black holes vomit out matter and how this influences their home galaxies.
