"Theorists speculate that the universe was a dark place for the first few hundred million years, before the first stars and galaxies formed," said lead author Dr Nicolas Laporte from Cambridge's Institute of Astronomy.
"Our observations indicate that cosmic dawn occurred between 250 and 350 million years after the beginning of the universe, and, at the time of their formation, galaxies such as the ones we studied would have been sufficiently luminous to be seen with the James Webb Space Telescope."
