New Study Challenges Understanding of Universe's Dawn

• A new study challenges the understanding of what ended the 'Cosmic Dark Age'.
• Scientists previously believed winds from exploding stars helped clear cosmic fog, but new findings show they block radiation.
• The study suggests astronomers may need to rethink a major aspect of cosmological evolution.
• The research focuses on events around 400,000 years after the Big Bang when the universe cooled enough to form atoms.
• The Hubble Space Telescope provided observations that led to this surprising discovery.
