How did they change the universe forever, and what can they tell us about its history and age? Well, you are in for a treat, because in this video, we will explore the amazing discovery of Maisie’s galaxy, one of the oldest and most distant galaxies ever observed. We will also learn how this galaxy challenges our current view of the universe and its age, and how it sheds light on the epoch of reionization, when the first stars and galaxies ionized the hydrogen gas in the early universe.
