Enormous 3D map of the universe shows brilliant 'sea of light' near the cosmic dawn

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.

Largest 3D Map Reveals Hydrogen Glow of the Early Universe

Astronomers have created the largest-ever three-dimensional map of hydrogen emission from the early universe, offering a new view of cosmic structures formed billions of years ago. The map covers a period roughly 9 to 11 billion years in the past, during the universe’s “cosmic noon,” when star formation activity reached its peak. The map was produced using data from the Hobby-Eberly Telescope Dark Energy Experiment (HETDEX), which studies the fa…

Astronomers Create the Largest 3D Map of the Early Universe’s Hydrogen Glow

Astronomers created the largest 3D map of hydrogen emission from the early universe using data from the Hobby-Eberly Telescope Dark Energy Experiment. The map reveals large cosmic structures during the universe’s peak star-forming era about 9–11 billion years ago.
