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.
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 ...
