Hubble Reveals a Surprising Twist in How the Early Universe Became Transparent

New Hubble Space Telescope observations are challenging scientists’ understanding of how the early universe became transparent. Surprisingly, galaxies with the fastest winds appear to trap more radiation rather than release it. The findings suggest that young stars may have helped clear the primordial hydrogen fog before supernova explosions reshaped these galaxies. Could this change what we know about the universe’s earliest evolution? Thank you for listening to Bedtime Astronomy — your guide to the cosmos.
