Besides the study you are taking, there are opportunities to take extra courses at Leiden University. Here you will find some opportunities to take extra education.

They hurtle along at over a thousand kilometres per second: the fastest stars in the Milky Way. PhD candidate Fraser Evans conducted research into these elusive hypervelocity stars and discovered that they have a lot to teach us, about black holes and supernovae, for example.

The excuses for the slavery past? It would have been better if the cabinet had taken some more time on that, thinks university lecturer and Atlantic slavery expert Karwan Fatah-Black. 'Too bad they didn’t wait for the results of the study.'

ESA’s space telescope Gaia, which maps the Milky Way, completes its active phase of scanning the sky on 15 January. Over the past decade, Gaia has made more than three trillion observations of about two billion stars and other cosmic objects. ‘Gaia is already the discovery machine of the decade,’ Leiden…
