For the first time, astronomers have managed to take a photo of a supermassive black hole and its shadow. They used the Event Horizon Telescope (EHT), a worldwide network of eight radio telescopes that together form a virtual telescope the size of the earth. The news was presented in six press conferences…

Piet van der Kruit, whose PhD supervisor was Oort himself, has written a biography about…

De decentralisaties van de zorg aan langdurig zieken en ouderen, jeugdzorg, en werk en inkomen die vanaf 2015 zijn doorgevoerd in Nederland hebben geleid tot een transitie van een centraal naar een lokaal stelsel van zorg en welzijn. Deze transitie beoogt zorg en ondersteuning dichter bij de inwoners…

‘I got into Nature last year, I was nominated for a faculty teaching award and my kids don’t care. But if your simulations get on The Big Bang Theory then that’s something!’ says Huib van Langevelde.

For only the second time ever, astronomers have linked a neutrino to an object outside our Milky Way. These observations were made using telescopes both on Earth and in space. The researchers, including Leiden astronomer Sjoert van Velzen, were able to trace the neutrino to a black hole that is devouring…

“Het is niet genoeg dat Amerika aanwezig is in de ruimte. Amerika moet domineren”, zegt Donald Trump tijdens een bijeenkomst met de Nationale Ruimteraad. Zodoende wil hij naast de land-, zee-, en luchtmacht een nieuwe militaire kracht oprichten: de Space Force. Ruimterecht deskundige Tanja Masson denkt…

The Dutch women’s movement began around 1967 with the discussion of the disadvantages that women faced in daily life. In 1968 the MVM (Man-Vrouw-Maatschappij) was born and played an important role as a public voice demanding female education programs and inclusion in the workforce.

LUC hosts many opportunities for students to join activities during their study. Within the college, there are numerous initiatives that you can choose from and if it doesn't exist yet, try making it yourself!

The zoo of detected exoplanets reveals both the uniqueness of our own Solar System and the complexity of planetary system formation, sparking fundamental questions about how planetary systems form and evolve.

At Leiden Observatory, researchers investigate the origin of stars and their planetary systems. They detect and characterize planets around other stars, which are called exo-planets. They study how stars and planets form. And they follow molecules from interstellar clouds to nascent planet systems.…
