Light-propelled winds help explain bright early galaxies seen by Webb
Light-propelled winds help explain why Webb found so many bright galaxies in the early universe.
Astronomers examining images of the early universe from the James Webb Space Telescope found an overabundance of bright galaxies.
Based on what they knew about the early universe, such galaxies should have been far less common in the few hundred million years following the Big Bang. Light-propelled winds help explain the finding.
