In the beginning was light – around 13.8 billion years ago, the Big Bang marked the beginning of the history of our cosmos. How could stars and galaxies suddenly appear out of the darkness? What did the light of the first day look like? Hans-Walter Rix has been asking himself these questions for over two decades. The James Webb Space Telescope, which has been floating in space since 2021, is now sending images that he has been awaiting for years. They show what the universe looked like after the Big Bang and provide unprecedented insights into the galaxies. The lecture takes us on a journey through the history of the universe and explains how many stars were already part of the first galaxies and whether we now have to rewrite the Big Bang theory.
