Infographic depicting a timeline of the universe. Labeled events include: the Big Bang about 13.8 billion years ago; Cosmic Microwave Background around 13.7 billion years ago; the Cosmic Dark Ages around 13.6 billion years ago; the Era of Reionization starting about 13.5 billion years ago; and then present-day galaxies. On the top of the graphic there is an icon representing the James Webb Space Telescope. A wavy line representing Webb's infrared vision extends to the Era of Reionization period, showing that Webb can look back in time at 13.5 billion years of cosmic history.
