A unique technique allowed astronomers to see the early universe as a "sea of light" and explore the effects of gravity and ...

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 ...

If you think a galaxy is big, compare it to the size of the universe: it's just a tiny dot which, together with a huge number of other tiny dots, forms clusters that aggregate into superclusters, ...

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

Astronomers have created an enormous 3D map of the universe revealing a glowing “sea of light” from hydrogen gas during the cosmic dawn nearly 11 billion years ago.

Astronomers have unveiled one of the most ambitious maps yet of the early universe, revealing a vast "sea of light" between galaxies that had remained otherwise hidden in previous surveys.

The space between galaxies is not empty. In a new map of the early universe, those “blank” stretches take on a faint, hydrogen-blue glow that had mostly escaped surveys until now.

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