The Hubble space telescope has peered back to the dawn of cosmic time and detected light from a star that existed within the first billion years after the Big Bang — which is a new record. Astronomers said Wednesday that the newly discovered star, called “Earendel,” is so far away its light has taken 12.9 billion years to reach Earth, when the universe was seven percent of its current age. Astronomers intend to gaze at the star using the James Webb Space Telescope, Hubble’s successor in order to confirm Earendel’s age, mass, and radius.
