Kaiser Spring Lectures 2019

This is an annual series of public lectures at the location that forms the heart of astronomy in Leiden: the Old Observatory.

In this monumental observatory, located in the botanical garden of the University, every year we invite a number of researchers in astronomy to tell us in an understandable way about their fascination and their research. Here you can listen to all the interesting phenomena and events that make our existence here on Earth possible, either for yourself or as an outing with your friends, family and others. No prior knowledge is required for these lectures!
