Exclusive: astronomers surprised at size of 13bn-year-old object, which raises new questions about where black holes came from
Astronomers have detected the oldest black hole ever observed, dating back more than 13bn years to the dawn of the universe.
The observations, by the James Webb space telescope (JWST), reveal it to be at the heart of a galaxy 440m years after the big bang. At around a million times the mass of the sun, it is surprisingly big for a baby black hole, raising the question of how it grew so big so quickly.
