  "summary": "The Epoch of Reionization is when radiation from early galaxies and their stars reionized neutral hydrogen and let light travel freely through the cosmos. Some research shows that supernovae helped the process. But new research shows that, though they may have helped initially, supernovae eventually slowed reionization.",
