James Webb Space Telescope Spots Source of ‘Extreme’ Redshift 7 Ultraviolet Light Powering Cosmic Reionization

Scientists studying data collected by the James Webb Space Telescope believe they have identified extremely bright galaxy clusters formed in the redshift 7 phase of the galaxy’s development as the source of extreme levels of ultraviolet light that powered a period of cosmic renovation known as reionization. The mysterious origins of this reionization process have long baffled astronomers and cosmologists. The new research says these small, yet powerful galaxies underwent extreme star formation events called starbursts that were able to generate sufficient ultraviolet light to clear a path through the universe’s early interstellar galactic clouds, resulting in reionization. “When it comes to producing ultraviolet light,
