A study of the fascinating galaxy system nicknamed "The Stingray" suggests that mysterious little red dots could be a phase ...

Although magnetic forces are usually much weaker than gravity in shaping cosmic structures, the findings suggest that strong, ordered magnetic fields may have emerged earlier than expected. Over time, ...

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 ...

Astronomers have long argued that dark matter is the invisible scaffolding that holds galaxies together. Without its immense ...

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 ...

For the first time, scientists have reconstructed the full history of a galaxy outside the Milky Way using chemical clues. By analyzing oxygen across NGC 1365 and comparing it with simulations, they ...

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 ...

Through the SPS summer internship program, physics undergraduates like MJ Keller are placed in organizations where they apply ...

How do you find a galaxy that never formed? The standard cosmological model predicts the existence of “failed” galaxies — clumps of dark matter that captured gas but never birthed a star. Because they ...

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 ...
