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 ...

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

Astronomers discover PicII‑503, a 14-billion-year-old star carrying primordial elements, challenging theories of early star ...

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 ...

Researchers have identified a potential mechanism that explains how turbulent plasma can produce the vast, ordered magnetic fields observed across the universe Cosmic magnetic fields are everywhere, ...

Scientists have uncovered evidence that our Sun may have traveled across the Milky Way as part of a massive migration of ...

The XRISM spacecraft has captured the dramatic awakening of a supermassive black hole, IRAS 05189-2524, as it fires cosmic ...

Discovered in the Pictor II dwarf galaxy, star PicII-503 has an extreme deficiency in iron—less than 1/40,000th of the sun. This signature makes it the clearest example of a star within a primordial ...

Still in its original galaxy, a rare holdout from the second generation of stars sheds new light on the origins of the elements—and how massive supernovae reshaped the cosmos ...

Like tiny photobombers, cosmic anomalies resembling small, bright red points show up in almost every snapshot taken by the ...
