Astronomers want to understand the Universe, from the Big Bang to the present day, and what the future will hold. In Leiden they focus on two key questions: ‘How did stars and planets originate’ and ‘How were galaxies and black holes formed in the young Universe?’ A new generation of telescopes – just…

In 2020, many of our staff and students have again won prestigious prizes and been awarded important research subsidies.

The Leiden wall formulae, Einstein's sink or the signature wall of Ehrenfest. It are just a few of Leiden's hidden science treasures. Alumnus from the Leiden Observatory Alex Pietrow described a few of these places on travel website Atlas Obscura.

Which teacher did an outstanding job in not only transferring knowledge in novel ways but also in getting students enthusiastic and connecting a course to current research themes? Meet the nominees for the Teacher of the Year Award 2023!

A comprehensive analysis of the state of play, the design of monitoring mechanisms, and creation of a toolbox of support measures.

Smart algorithms and powerful processors are just as essential for astronomy as big telescopes. Astronomers at Leiden University therefore constantly operate at the interface between astronomy and data science.

The Faculty of Science has multiple study associations, which organise both study-related and social activities for students.

By effectively integrating word-class scientific research and excellent education, you will become a professional astronomer with an internationally recognized degree.

By effectively integrating word-class scientific research and excellent education, you will become a professional astronomer with an internationally recognized degree.

The Biological- and Soft-Matter Physics Master specialisation is one of the two programmes Leiden offers in experimental Physics. The programme can to a high degree be tailored to individual needs and interests.

By effectively integrating word-class scientific research and excellent business education, you will become a professional astronomer with an internationally recognized MSc degree prepared for technological business challenges.

Review Committees, with cross-boundary experts, are invited to assess our research and education programmes.

Three major cosmology-focused missions are planned for the next decade: the Euclid space telescope, the Vera C. Rubin Observatory in Chile, and the Nancy Grace Roman Space Telescope.

Are there other planets like the earth, and will there also be life? Astronomers study planets around stars other than the sun, with the aim to find out what kind of gasses their atmospheres are made up with.

Ecotox is located in an ambitious surrounding at the Leiden University. It is an initiative of both institutes Institute of Environmental Sciences (CML) and Institute of Biology Leiden (IBL).

This is a yearly event where we move in one week from the physics of light through the composition of the microscope, fluorescence microscopy and end up with some image analysis All the lectures are backed by practicals to really put your obtained knowledge into practice

Kamerlingh Onnes Building, Steenschuur 25, 2311 ES, Leiden

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

Leiden Law Academy (LLA) organises professional conferences for Leiden Law School. These vary from one day to multiple days.

Leiden University research institutes based in Leiden and The Hague.

The aim is to discover where differently shaped metal nanoparticles distributes in Danio rerio, linking the distribution with genomic responses and so come up with a Mode of Action.

The goal of target discovery is to identify and validate proteins and biological pathways that are involved in the disease process. Modulating these target proteins and pathways with small molecules, therapeutic proteins or other biomolecules (e.g. mRNA) could deliver an effective and safe drug or v…

FIJI is one of the most used image analysis tools in the world. FIJI stands for FIJI is just ImageJ, it is however much more.

The Astronomy and Science Communication and Society programme trains you in practical and theoretical aspects of science communication alongside high quality astronomical research at a world class institute.

This is the physics summer school of Leiden University. It is part of the Leiden Institute of Physics (LION). The summer school is intended for Bachelor (BSc) students in physics. It covers topics from quantum matter and optics, to biological & soft matter physics and cosmology and theoretical physics.…

The Education Office Astronomy supports all aspects of the Astronomy bachelor and master education programmes. Its main focus is on education quality assurance, student monitoring, education-related PR, student recruitment, job market orientation and alumni policy.

The mission of our group is understanding how science communication works to improve the interaction between science and society. We believe better science communication can improve our society and engage many different groups with science, also improving science.

This thesis aims to demonstrate how the achromatic nature and design flexibility of liquid-crystal optics can be used to improve high-contrast imaging instruments to facilitate detailed exoplanet characterization.

The Gorlaeus Building will be constructed in three phases, with the new building due to be completed by 2028.

The Centre for Science and Technology Studies (CWTS) is an interdisciplinary research institute at Leiden University that studies scientific research and its connections to technology, innovation, and society.

On behalf of the Dutch astronomical community, we unequivocally condemn the brutal killings of Ahmaud Arbery, George Floyd, and Breonna Taylor and countless others and instances of racism.

This is an Erasmus+ International Credit Mobility project of Leiden University’s Faculty of Science with two Armenian universities, Yerevan State University and Byurakan Astrophysical Observatory.

The structure of bacterial cells provides crucial clues about their interaction with their host. What are the key structural features of a bacterial cell that determine pathogenicity? What roles do these structures play in the life cycle, and how do they change during the infection process?

The 11th edition of Leiden Museum Night will take place on Saturday 18 May 2019. Nine museums will once again be opening their doors. As it is Leiden University’s 444th anniversary this year, we will be celebrating in style at the Academic Historical Museum.
