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 ...

What Looked Like a Planet Was Actually a Massive Space Collision So, imagine astronomers are looking at something, thinking, ‘Wow, cool planet!’ Then, bam! Turns out it wasn’t a planet at all, but a ...

How fast can a galaxy build ordered magnetic fields spanning thousands of light-years? Existing theories say several billion years, but observations of galaxies in our universe imply shorter ...

A nearby galaxy is undergoing a major transformation, and astronomers are watching the process unfold in real time ...

Using a novel technique that examines the motion of two nearby galaxy groups within their surrounding cosmic flow, an international team led by David Benisty of the Leibniz Institute for Astrophysics ...

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 ...

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, ...

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

Astronomers have uncovered a hidden cosmic web of galaxies and gas by mapping hydrogen light from the early universe.

Despite years of debate and follow-up studies, an odd streak of cosmic light still defies a final explanation. Is it a giant ...

A new study, published in The Astrophysical Journal, finally changes that. Using data from the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX), researchers built a three-dimensional map of ...

New 3D map of the early universe from HETDEX reveals faint hydrogen light linking galaxies 9 to 11 billion years ago.
