A group of astronomers has robustly timed the end of the epoch of reionization of the neutral hydrogen gas to approximately 1.1 billion years after the Big Bang. Reionization began when the first generation of stars formed after the cosmic “dark ages,” a long period when the Universe was filled with neutral gas alone witho
