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…

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…
