"Groundbreaking Video Captures First-Ever Glimpse of Cosmic Web's Interstellar Light"

Astronomers have captured the faint glow of the cosmic web, the largest structure in the universe that connects galaxies, for the first time. This breakthrough provides valuable insights into galaxy formation, evolution, and the elusive dark matter. By using the Keck Cosmic Web Imager, researchers created a 3D map of the cosmic web by detecting emissions from hydrogen gas. The images reveal the crisscrossing filaments of the cosmic web, which feed galaxies with gas for growth and star formation. This discovery opens up new possibilities for studying the universe and understanding its origins.
