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

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

A newly discovered galaxy cluster could rewrite our understanding of the cosmos, as scientists spot 'something the universe wasn’t supposed to have’. Researchers found that the cluster was burning ...

Astronomers seem to have pulled back a new curtain on the early universe. A massive 3D map now shows a "sea of light" that had been mostly invisible until recently. It’s not galaxies alone lighting up ...

Scientists have released a new study that catalogues the universe by mapping huge clusters of galaxies. These clusters are some of the largest known objects in the universe — and they can help ...

Two new studies have measured the expansion of the universe in our immediate cosmic neighborhood using a novel method that ...

The Vera C. Rubin Observatory has started releasing its first discoveries: including supernovae, variable stars and asteroids ...

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 ...
