Every month there is an opportunity to visit the Old Observatory in the evening. These open evenings consist of a lecture followed by a visit to the telescopes in the building.

Astronomer and Marxist Anton Pannekoek was a remarkable figure. This book aims to study the connections between his life as a socialist theorist and as a pioneering scientist through the prism of Pannekoek's biography.

What does it mean for a citizen to be ‘literate’ in astronomy? Astronomers who participate in outreach to the general public experience various degrees of astronomical knowledge among people. But so far, there had not been a systematic evaluation and definition of what astronomical literacy actually…

This summer, the Universe is closer than ever. With the online astronomy summer programme Space in Your Living Room!, the Leiden Observatory brings astronauts and Leiden astronomers to the homes of children all across Europe.

An international team of astronomers has published a map of the sky showing over 25,000 supermassive black holes. The map, to be published in the journal Astronomy & Astrophysics, is the most detailed celestial map in the field of so-called low radio frequencies. The astronomers, including Leiden astronomers,…

Dust particles in space form the basis for new stars and planets. But what do these particles consist of and how do they behave? Sascha Zeegers studied this. PhD defence 1 November.

In addition to the walk-in tours at the visitor center, we also offer private tours for groups. These tours delve deeper into the history of the building, but also offer the opportunity to learn more about astronomy in general.

The Old Observatory has a rich history. On this page you will find a short version of the history that took place in the observatory.

Leiden University regularly confers honorary doctorates, and presents awards and prizes.

By adding their signature to the collaboration agreement on 31 May, Leiden University, TU Delft, space research institute SRON and NWO confirmed the move of SRON from Utrecht to South Holland. From 2021, the headquarters of the space research institute will be located on the Campus of Leiden Univ…

‘What if we switch off all the lights one evening? That idea crossed my mind from time to time. And when I mentioned it to a taxi driver one day, he said: “Oh, you mean: lights out, stars on!” That’s not completely true, of course, because the stars are always on, but his phrase summed up the idea n…

The Computer Science and SCS master specialisation gives you the opportunity to combine fundamental research in computer science with different aspects of science communication.

The Computer Science and Education master specialisation gives you the opportunity to combine computer science research with an excellent education in becoming a teacher.

Why do flowers often smell so wonderful? And some other plants are very horrible? Come smell it, see it and discover it in the visitor center in the Old Observatory. Suitable for young and old.

This interdisciplinary minor addresses sustainability challenges from a systems perspective, and investigates ways to sustain society within planetary boundaries.

Leiden Professor of Astronomy Mike Garrett is searching for signs of extraterrestrial intelligence. In his Kaiser lecture on 23 April he will discuss how far science has progressed in this quest.

The Leiden Institute of Advanced Computer Science (LIACS) offers bachelor and master level education in computer science at Leiden University. We are known for our scientifically based education and for our open atmosphere.

Our current research focusses on the exploration of the Universe using the neutrino. This neutral, almost massless and only weakly interacting particle can open a window to the distant Universe and also dense regions from which photons cannot escape.

Stellar feedback is a crucial ingredient in the evolution of galaxies.

Pre-University Classes are intended for high school students who want to do more than is offered in the regular school curriculum. In the classes, students follow special lecture series and through that are introduced to the world of science.

The specialisation Science Communication and Society (SCS) concerns science communication in a broad sense. The program focuses on the link between science and society and covers knowledge and skills in the field of science communication.

The civilizations of ancient China and Mesoamerica, although not historically related and obviously different in many specific aspects (such as language and writing), show many interesting commonalities and similar tendencies in their cultural manifestations.

The Leidse Weer en Sterrenkunde Kring (LWSK) is a society of amateurs interested in astronomy, space travel and meteorology. The association organises a monthly lecture on a fascinating subject, given by an expert in the field.

The programme offers you the ability to combine experimental research with theoretical courses. The programme helps you grow into an independent and skilled physicist.

Quantum Information Science & Technology (QIST) encompasses the understanding, design, construction and investigation of quantum information processing systems, such as quantum computers, quantum communication networks, and quantum sensors.

The programme guarantees a thorough experience on the frontline of physics research with a practical training of communicative and computer skills.

The programme guarantees a thorough experience on the frontlines of physics research AND data science. It focuses on research areas where these fields overlap and in the process provides practical training of communicative and computer skills.
