These halos, crucial to understanding galaxy formation, were largely unknown until the Hobby-Eberly Telescope Dark Energy ...

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 ...

A violent collision between two dwarf galaxies strips them of their dark matter.

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, ...

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

An international team led by UNIGE shows that red and dead galaxies can be found only 700 million years after the Big Bang, indicating that galaxies stop forming stars earlier than predicted by models ...

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 ...

A galaxy is a massive, gravitationally bound system. It contains stars, stellar remnants, interstellar gas and dust, and a ...

New findings from a large survey of galaxies suggest that star formation is largely driven by the supply of raw materials, rather than by galactic mergers that trigger sudden bursts of star formation.

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

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 ...
