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 “Lyman-alpha” light emitted by energized hydrogen, scientists used an advanced technique called line intensity mapping to capture not just the brightest galaxies but also the vast cosmic structures surrounding them.
