A Mighty Wind Blew Away Gas and Made Early Galaxies Brighter
Source: Universe Today ·
When astronomers looked at photos of the early universe taken by the James Webb Space Telescope, they found something odd: an overabundance of bright galaxies about 400 to 500 million years after the Big Bang. But these galaxies should have been far less common so soon after the Big Bang. Researchers may have figured this out: Powerful ultraviolet (Lyman-alpha) radiation produced by dense clusters of young stars acted like a leaf blower, driving light-blocking gas and dust out of the galaxy and thereby making the galaxies appear brighter.
