During the bachelor’s programme Astronomy you will immerse yourself in questions about our universe. Questions such as: ‘what happens in a black hole?’ and ‘what is dark matter?’ In doing so you will learn to apply mathematics and physics to astronomical problems and you will work with computer simulations…

The main goal of the THEOR CHEM group, headed by Prof. Geert-Jan Kroes, is to characterize, and to accurately predict the outcome of chemical reactions at gas-solid and liquid-solid interfaces. Here the solid surface is typically a metal or an ice surface. These goals are important to many areas in…

Professor Ewine van Dishoeck, together with an international team of colleagues, has written an overview of everything we know about water in interstellar clouds thanks to the Herschel space observatory. The article, published in the journal Astronomy & Astrophysics, summarizes existing knowledge and…

An international team of astronomers led by researchers from the Leiden University has discovered a whirlwind of dust and pebbles in orbit around a young star. It is possible that a planet is forming in the pebbles. The team of scientists made the discovery during the time that designers and developers…

A moon rock from the Apollo 17 mission, antique globes and the cosmos according to Wassily Kandinsky. Ewine van Dishoeck, Professor of Molecular Astrophysics, has put together an impressive exhibition at Rijksmuseum Boerhaave.

The Netherlands Organisation for Scientific Research has awarded Leiden astronomer Giovanni Rosotti a Veni grant for research into very young exoplanets. This grant offers young researchers the possibility to develop their innovative ideas for a period of three or four years.

An international team of astronomers led by scientists from Leiden Observatory has for the first time characterised a dust disk surrounding a young super-Jupiter, which is either a giant planet or brown dwarf. They detected infrared emission from the disk which might indicate that moons may have formed.…

Large telescopes can look so deep into the Universe that they can also look back billions of years in time. From 2018, the successor of the Hubble Space Telescope, the James Webb Space Telescope, will be able to see the period just after the Big Bang, when the first stars and galaxies formed. Astronomers…

Bernhard Brandl, the new Leiden Professor of Infrared Astronomy, is developing instruments for the world’s largest telescopes. These telescopes can be used to observe objects in space that are more than 13 billion years old. Brandl will deliver his inaugural lecture on 26 September.

How do religious narratives persuade their readers to believe their message? And how can it be that some readers even come to treat fantasy and science fiction as authoritative religious texts? These are the core questions treated in Markus Davidsen’s new book Narrative and Belief: The Religious Affordance…

Humans have influenced nature since as early as the Ice Age, and over the past century man’s impact has become even greater with our many new technologies and a growing world population. Leiden researchers study this impact and how we can keep it within reasonable limits so that nature can be preserved.…

Over the past years it has been discovered that the population of extra-solar planets is large and diverse.

A night sky of more than 40 petabytes in size, simulating young star clusters and understanding how the body inhibits viruses: three Leiden projects have received computing time on one of the national computer systems.

In our teaching we give all our students the opportunity to become acquainted with sustainability themes and issues, where possible in line with the content of their programme.

Astronomers at Leiden University have discovered the first planets using a new instrument: the planet hunter MASCARA. This instrument, developed at Leiden Observatory, looks specifically for planet transitions around the brightest stars in the sky, which surprisingly enough have so far have hardly been…

How did dynastic organization – that it, the employment of non-ruling family members and the development of dynastic traditions and concepts – influence state formation in both Catholic Europe and Muslim West-Asia?

Undaunted by the corona crisis, Renske Donkers, a student of Molecular Science and Technology, conducted her bachelor’s research in collaboration with an international university. Her contacts with her supervisors at the University of Limerick, in Ireland, were all online. Donkers contributed to resolving…

The role of culture and diverse knowledge systems needs to be recognized when assessing nature’s contributions to people, a new policy forum paper in Science states. Alexander van Oudenhoven and thirty global experts present a new approach that will increase the effectiveness and legitimacy of policies…

The new MASCARA-facilty in Chile has achieved first light. This new facility will seek out transiting exoplanets as they pass in front of their bright parent stars and create a catalogue of targets for future exoplanet characterisation observations.

For the first time, international researchers have mapped the network of bacteria on coral reefs. They write about it in Nature Communications (9 April). Professor by special appointment Nicole de Voogd (Naturalis Biodiversity Center & Institute of Environmental Sciences) and two of her PhD students…

Two black holes, in close orbit around each other. Have they slowly drifted together, or did they emerge from two orbiting stars? Together with to colleagues form Amsterdam, Leiden astronomer Simon Portegies Zwart calculated that the second scenario is rather likely.

An international team of astronomers have become the first in the world to detect isotopes in the atmosphere of an exoplanet. It concerns different forms of carbon in the gaseous giant planet TYC 8998-760-1 b. The research will be published in the scientific journal Nature on Thursday.

From black holes to artificial intelligence and from drug research to data science: welcome to the fascinating world of the Faculty of Science. Our researchers, students and guests regularly give public lectures about their work. You are welcome to attend.

The Delivery of Biotherapeutics research group is led by Prof. Matthias Barz and focusses on the synthesis and characterization of polypept(o)ids and their application in nanomedicine to improve existing therapies or enable novel diagnostic or therapeutic approaches.

In the 16th and 17th centuries, many Northern-Netherlandish artists drew outdoors to train their hands and eyes, and to record landscapes and nature. In her inaugural lecture on 21 March 2022, Yvonne Bleyerveld, Professor by Special Appointment of Art on Paper and Parchment, draws our attention to a…

Leiden University has taken eighth place in this year’s SustainaBul, the sustainability ranking for universities and universities of applied sciences in the Netherlands. It was in 18th place last year.

On Friday, June 12th, the Europa Institute held its annual PhD Day.

Strengthening nature and at the same time investing in future-proof agriculture. That is the task of the Minister for Nature and Nitrogen, Christianne van der Wal. It is also the lifework of Leiden professor Jan Willem Erisman. He has been researching nitrogen for his entire career and has shown that…

Fluctuations in individual plant communities contribute to the stability of an ecosystem as a whole, a study published in Ecology Letters shows. Nadia Soudzilovskaia and colleagues for the first time used data from plant communities across five continents to prove this hypothesis.
