Even with state-of-the-art technology, it is almost impossible to see: a cosmic neutrino. Yet scientists have managed to image this particle with a deep-sea telescope. And that could help to better understand our universe. Leiden particle physicists collaborated on this ambitious project, published…

The Plants & Planets exhibition brings two worlds together in a dazzling mix of science, nature and art. It opens at Old Observatory Leiden and Hortus botanicus on 7 February.

Ten Leiden students have received a prize from the Royal Holland Society of Sciences and Humanities (KHMW). They were nominated by their degree programme. Who are these students?

Personal development, Working effectively

A delegation from the University of Edinburgh recently visited Leiden University to deepen their collaboration. What makes Edinburgh such an attractive partner?

To mark the university’s 450th anniversary, the Leiden Discoveries science route has been updated and was relaunched on the Night of Discoveries. New signs in town and a revamped website tell Leiden residents and visitors the stories of the city’s spectacular discoveries.

By looking at what is different, researchers often discover the special, the unusual. And that has already brought a wealth of highlights – also in Leiden.

For the first time, we’re seeing what Euclid sees. The telescope’s initial observations have provided a wealth of new information about our universe. But according to cosmologist Alessandra Silvestri, this is just the beginning. The research helps us gain a deeper understanding of the past, present,…

Welcome to Leiden University

Following in the footsteps of Professor Jan Zaanen, visiting fellow Louk Rademaker is exploring quantum effects in so-called strange materials. His research is paving the way for new materials that could be used in emerging technologies.

What will happen if the lights in a large part of the city are switched off? How many stars can you see without all that light pollution? This is what researchers, artists and the residents of Leiden are going to investigate during Seeing Stars Leiden on 25 September. ‘Leiden is the ideal place for…

Due to its success, the Leiden2022 Q&A has been extended and is looking for even more thought-provoking, interesting or unusual questions.

A discount on textbooks is always welcome. But for these students joining a study association has meant much more than that alone.

How has evolution shaped our curiosity? And how does that curiosity ensure that we now have the technological ability to discover whether we are alone in the universe? This was all covered during the celebration of Leiden University’s 449th Dies Natalis.
