Even though more than 4000 extra-solar planets are known today, only a small fraction of these has been captured in an image. To better understand the planet formation mechanisms in solar-like environments we started the Young Suns Exoplanet Survey (YSES).

Physicist Christopher Berg Smiet, who recently obtained his PhD in Leiden, has been awarded an NWO Rubicon. The grant allows him to conduct postdoctoral research for two years at the Princeton Plasma Physics Laboratory (PPPL) in the United States.

The Leiden Observatory is starting a crowdfunding campaign to raise enough money to construct a new telescope.

A team of astronomers led by Dutch scientists have directly imaged a giant planet orbiting at a large distance around a sun-like star. Why this planet is so massive, and how it got to be there, is still a mystery. The researchers will publish their findings in the journal Astronomy & Astrophysics.

The entrepreneurial spirit is highly present among the SBB students. The many (successful) spin-off companies from Leiden University brought by (former) SBB students are proof of this.

Staring into the clouds hoping for a glimpse of the sun, cheering in encouragement, video recordings: there was no shortage of things to do at the Leiden Observatory. More than 600 visitors witnessed the last, almost complete solar eclipse of the decade..

A team led by Leiden University in the Netherlands and the National Radio Astronomy Observatory have, for the first time, robustly detected semi-heavy water ice around a young sunlike star. In this ice, some of the ordinary hydrogen atoms have been replaced by deuterium, a heavier variant of hydroge…

The focus of this thesis is how stars like our Sun and planets like Jupiter, Saturn, and Earth are formed.

ALMA has observed stars like the Sun at a very early stage in their formation and found traces of methyl isocyanate - a chemical building block of life. This is the first ever detection of this prebiotic molecule towards solar-type protostars, the sort from which our Solar System evolved. The discovery…

Leiden University has partnerships in the local region, in the Netherlands, in Europe and with countries on almost all the world's continents. Students and researchers benefit from these partnerships, but society is also a beneficiary, says Rector Carel Stolker.

The solar system was formed approximately 4.56 billion years ago. Despite the numerous theories that have been developed over the years, the formation and evolution of the solar system still remain unclear.

As South Korean president Moon Jae-in prepares to leave office, North Korean leader Kim Jong Un has thanked him for trying to improve relations. Assistant Professor Christopher Green explains in the Calgary Sun what impact North Korea's gesture of goodwill might have.

Starting a PhD can be both exciting and overwhelming. To help you get off to a smooth start, you can find a few practical resources on this page.

On this page you will find the most important issues that you as a student of Leiden University will have to deal with.

Corrie Bakels is known as one of the founders of bio-archaeology in the Netherlands. One of her former students, Dr Marco Langbroek, active in astronomy, made a request to the International Astronomic Union to name a recently discovered asteroid after her. Hearing the news, Bakels was astounded. 'My…

An international team led by Leiden astronomers has taken the first-ever image of a young, Sun-like star accompanied by two giant exoplanets. The researchers used The European Southern Observatory’s Very Large Telescope for this, known as ESO’s VLT. Images of systems with multiple exoplanets are extremely…

Great that you are interested in one of the master's programmes of Leiden Law School. Apply before 15 June if you would like to start your master's programme this September. For students who expect to graduate with a bachelor's degree in Law (LL.B.) from Leiden University before the starting date in…

‘Take science communication more seriously.’ This is the message that Ivo van Vulpen, professor by special appointment in Science Communication in Physics, wants to convey during his inaugural lecture. At the moment, a lot of researchers look down their noses at this while it is extremely important…

At LUC we are very excited for your arrival this August, and are eagerly preparing everything for your move-in day and a fantastic introduction week. This site will give you all the information you need about the introduction week, as well as the practical information you need before moving to The…

No sitting in lecture halls, no coffee at the JuCa: Leiden Law School students will have to follow lectures and do exams from home for the time being. A huge transition.

Thousands of first-year students and hundreds of mentors kicked off the EL CID on Monday morning. This year for the first time, the introduction week of Leiden University and Leiden University of Applied Sciences was also open for students of Regional Training Centre mboRijnland and the Leiden Instrument…

A Humanities degree gives you a solid start on the job market, as shown by the employment survey among alumni who graduated from 2020 through 2024.

Using the James Webb Space Telescope, an international team of researchers, including Leiden Professor of Molecular Astrophysics Ewine van Dishoeck, has discovered a palette of hydrocarbons in a planet-forming disc around a young, low-mass star. The results confirm that discs around very lightweight…

From chilling on the beach to a speech by the mayor. HOPweek is a speedy way for hundreds of ‘Leiden’ students who are going to be studying in The Hague to get to know each other. Many of them come from abroad. ‘I actually dare to cycle here.’

Astronomers led by Leiden PhD candidate Richelle van Capelleveen have, for the first time, discovered an exoplanet that has carved a bright gap in the protoplanetary disc around its star. This rare observation provides new insights into how young planets shape their surroundings.

The Career Service Humanities offers assistance while you’re a student and for a year after you graduate! We can help you with:

If you're considering starting the master’s in February, please take into account that the programme may be adapted if fewer than 12 students enroll. In that case, you'll begin with an intensive crash course designed to provide essential foundational knowledge. Read below what the adapted program will…

Rainbow flags, funky sounds and drag queen Petty Libel: the very first Canal Pride Leiden has become reality. Leiden University joined the parade with a packed and buzzing boat. ‘The Leideners were really supportive and gave us a great response.’
