First there was the Big Bang, the point when the Universe and even space and time were created out of the void. And after that there was darkness – because the Universe contained little more than hydrogen and helium gas. It was not until a few hundred million years later, after the first stars were formed, that anything became visible. This thirteen-billion-year-old light is still en route to us and can be received by our telescopes.
The ‘early’ Universe is an important research theme in Leiden astronomy. Hardly surprising, as the origin and evolution of stars, galaxies and black holes largely determine the history and the future of the Universe.
Astronomers want to understand the Universe, from the Big Bang to the present day, and what the future will hold. In Leiden they focus on two key questions: ‘How did stars and planets originate’ and ‘How were galaxies and black holes formed in the young Universe?’ A new generation of telescopes – just operational or still under construction - will help them find the answers. Maybe we will even detect signs of life on planets outside our solar system.
