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

The James Webb Space Telescope has turned its infrared instruments on the spiral galaxy NGC 628, producing the first spectroscopic survey of young star clusters still embedded in the dust clouds where ...

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 ...

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

This NASA/ESA Hubble Space Telescope image features a galaxy whose asymmetric appearance may be the result of a galactic tug of war. Located 35 million light-years away in the constellation Leo, the ...

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

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 ...

A groundbreaking study in galactic archaeology proves the Sun made a treacherous journey to reach its current home in the ...

If you’ve ever been to a place with minimal light pollution and looked skywards at nighttime, you’ve probably seen our Milky Way galaxy. It manifests as a thick, hazy band of stars streaking across ...
