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 ...

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 ...

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

Astronomers working with data from the Hobby-Eberly Telescope Dark Energy Experiment, known as HETDEX, say they have produced one of the largest and sharpest three-dimensional maps to date of ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

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, hydrogen-blue glow that had mostly escaped surveys until now. Astronomers working ...
