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

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 have unveiled one of the most ambitious maps yet of the early universe, revealing a vast "sea of light" between ...

A new study suggests that "little red dots" spied by the James Webb telescope could be the universe's short-lived first ...

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 ...

Ever since it began its operations in 2022, the James Webb Space Telescope has come across supermassive black holes from the early universe that had grown too big too fast to be explained by existing ...

Astronomers have found that both the core of our Milky Way and the earliest proto-galaxies in the universe share a surprising trait: They are unusually calm and quiet in terms of harsh radiation. This ...

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

Astronomers have released the largest-ever three-dimensional map of hydrogen emissions within the early universe. This map ...

A new three-volume study explores how quantum physics, gravitation and cosmology may be understood within a unified ...

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 ...
