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 ...

Astronomers used subtle warps in galaxy shapes to map the invisible forces shaping the universe. By reanalyzing years of telescope images, they studied more than 100 million galaxies across an ...

The largest-ever three-dimensional map of the cosmos, plotting out some 15 million celestial objects, could help reveal the ultimate fate of the universe. Astrophysicists know that the universe is ...

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 ...

Astronomers seem to have pulled back a new curtain on the early universe. A massive 3D map now shows a "sea of light" that ...

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 ...

Astronomers have created the largest and most detailed 3D map yet of a glowing signal from the early universe, revealing hidden galaxies and gas from 9-11 billion years ago. By analyzing faint ...

Four galaxies crowd the center of a collapsing structure 1.4 billion years after the Big Bang. Each one is churning out stars at a pace that defies comparison with the present-day universe. Around ...
