Unveiling the Enigmatic Glow of Early Galaxies
The mysterious source of Lyman-alpha emissions in the early Universe has been revealed by astronomers using the James Webb Space Telescope. They found that galactic mergers and abundant star formation in the early Universe created the emissions and provided a path for them to escape the dense, opaque neutral hydrogen. This discovery sheds light on the previously unexplained detection of light from hydrogen atoms in the very early Universe and opens a new window into understanding the early Universe.
