Exploring 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…

Star birth: a slow and mysterious drama
A star does not just appear in the sky overnight. Its creation takes tens of thousands of years. Twenty years ago, astronomers took a picture of a star in its birth phase. The James Webb Space Telescope (JWST) could now capture that same star in much greater detail. This does not only provide beautiful…

Vici grant for research on the formation of galaxies
How do galaxies form? That is what astronomer Mariska Kriek will be researching in the coming years. She received an NWO Vici grant of 1.5 million euros to study galaxies in the early universe. ‘This research uses new and unprecedented observations from the James Webb Space Telescope (JWST). These allow…

Gas-surface reaction dynamics and surface science
The local ordering of atoms at the surface of a metallic particle determines its catalytic activity and selectivity. As energy systems of the future will be based on efficient catalytic conversion of small molecules in closed cycles, we study how structural effects of catalysts can be used to our ad…
