The directorate of Leiden Observatory consists of the Scientific Director, the Director of Education and the Director of Operations.

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.

Is there extra-terrestrial life out there? It now looks as though we can sketch out an answer to this enduring question. Leiden Observatory is helping to build new instruments to find the most promising exoplanets.

An overview of awards and prizes granted to our staff and students in 2022, as well as special appointments at Leiden University and other institutions.

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.…

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

Dirk Uittenbogaard, a student on the Delft-Leiden Master’s in Industrial Ecology, has won a gold medal for rowing at the Olympic Games in Tokyo. Uittenbogaard took gold in the men’s quadruple sculls, together with Abe Wiersma, Tone Wieten and Koen Metsemakers.

Two Leiden scientists - Ignas Snellen and Bernhard Hommel - have been awarded an ERC Advanced Grant. The grant will fund their research over the coming five years on exoplanets and free will.

Welcome to the Leiden Science community! Throughout the year, our faculty hosts a range of events designed to bring together students and staff.

The Old Observatory in Leiden has reclaimed its most important telescope. Since the 1960s, the Meridian Circle (also known as a transit telescope) had been housed in the Boerhaave Museum. After more than sixty years, the telescope is finally back in its original location. Now, the public can enjoy it…

Four scientists will receive the TOP grant for Physical Sciences from the NWO (Netherlands Organisation for Scientific Research). They are astronomer Ignas Snellen, mathematicians Tim van Erven and Charlene Kalle and computer scientist Siegfried Nijssen. The funds will be used to finance temporary research…

Dutch astronomers have measured a superstorm for the first time in the atmosphere of an exoplanet, the well-studied “hot Jupiter” HD209458b. The very high-precision observations of carbon monoxide gas show that it is streaming at enormous speed from the extremely hot day side to the cooler night side…

Astronomers have discovered seven Earth-like planets around a dwarf star in our galaxy. Three of these planets are located in the habitable zone of this star, and may contain liquid water. ‘The next step is to study the atmospheres for signs of life. In Leiden we are experts in that area,‘ says planetary…

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…

On Monday 9 May Mercury will pass between the Earth and the Sun. This rare event can be followed in the Leiden Observatory. The Observatory's new solar telescope produces a very clear image and offers a unique opportunity to observe Mercury at the highest magnification possible in the Netherlands.

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.

‘I already gave a talk about planets when I was five.’ With the theme of the 3 October celebrations being ‘Jong geleerd is oud gedaan’ (meaning something like, ‘You’re never too young to learn’), this year’s 3 October University was especially for children. Many parents came with their offspring to…

A large delegation composed of 11 delegates from institutes from the Faculty of Science has made an extensive visit to China and enhanced Leiden’s influence in the Chinese academia, industry and local government.

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.

An international team led by Leiden astronomers has discovered why the two stars of binary star DI Herculis rotate so strangely around one another, which once even proved problematic for Einstein's theory of relativity. Their findings were published in Nature.

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 2023, many of our students and staff won great prizes and secured important research grants.
