Cosmic reionization viewed at a redshift of 9.3

Cosmic Reionization |  The box shows the distribution of neutral hydrogen (maroon) and ionized hydrogen (light blue) around the most energetic star-forming sources (yellow dots) in the very early universe (a redshift of 9.3). This image is a frame from an animation that illustrates the Science Nugget article in the second TMT Newscast.
