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 ...

The space between galaxies is not empty. In a new map of the early universe, those “blank” stretches take on a faint, ...

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

Scientists are championing a relatively new technique as a method to understand the structure of the early universe in three dimensions. With enough time and magnifying power, a telescope can gather ...

Using spectral data from the Hobby-Eberly Telescope at McDonald Observatory, astronomers have produced the most detailed 3D map yet of faint cosmic structures from 9-11 billion years ago, revealing ...

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

Astronomers working with data from the Hobby-Eberly Telescope Dark Energy Experiment, known as HETDEX, say they have produced ...
