The shock wave triggered by one of the five galaxies making up the iconic Stephan’s Quintet appears to be less disruptive than previously thought, with the shock likely being cushioned by dust particles in the surrounding gas. This is according to the analysis of the first scientific observations of…

Leiden emeritus professor George Miley receives an honorary doctorate from Trinity College Dublin on 8 December. ‘I never dreamed that I would receive an honorary doctorate somewhere, and this is all the more emotional because it's in the city where I spent the first 21 years of my life.’

Making all those things we normally cannot see visible is the challenge that fascinates Fons Verbeek, Leiden's new Professor of Computational Bio-Imaging. Contributions from chemistry, optics and in particular computational sciences to making and processing these images give greater insight into the…

On Thursday 25 January 2018 the Europa Instituut in Leiden hosted a round table session with the title “Securing the rule of law in Poland: which role for Europe?”. It was a small meeting bringing high-level experts together under Chatham House Rule.
