Astronomers have used the James Webb Space Telescope to catch an extraordinary glimpse of a massive galaxy taking shape in the early universe. They identified a compact group of at least six galaxies that are likely to merge into a single enormous system. At the heart of this cosmic construction site…

Donororganen zijn er nooit genoeg. De organen die wel beschikbaar zijn, moeten vliegensvlug getransplanteerd worden. De geneeskunde zet daarom volop in op het langer goedhouden van organen. Marlon de Haan (24) onderzoekt hoe je nieren buiten het lichaam in leven kunt houden.

Finally we know for sure that there is a black hole at the centre of our own galaxy. Today, astronomers unveiled the first ever photo of Sagittarius A*, a super-massive object at the centre of the Milky Way. This picture could only be taken thanks to the cooperation of telescopes worldwide.

An international team of astronomers led by Matus Rybak (Leiden University) has proven, thanks to accidental double zoom, that millimetre radiation is generated close to the core of a supermassive black hole. Their findings have been accepted for publication in the journal Astronomy & Astrophysics.

‘Space Antenna LISA will open an unprecedented window on the Universe,’ says astronomer Elena Maria Rossi. The mission will be the first one to detect Gravitational Waves from space. These can tell us more about the beginning of our Universe and the formation of black holes. With an NWO grant of twelve…

How are supermassive black holes born? That is the question astronomer Elena Maria Rossi is trying to answer. But how do you investigate something you cannot see?

Why is water wet? What is ADHD? In De Hoe?Zo! Show, curious 9-and-10-year-olds get answers to their questions. PhD candidates take to the stage to demonstrate just how exciting science can be while enhancing their own communication skills at the same time.

Wat zie jij als je verderkijkt? Hoe ziet studeren aan de Universiteit Leiden in 2075 eruit? We nodigen je uit om mee te doen met Verderkijkers.

Hoe kan het dat universele mensenrechten wereldwijd niet hetzelfde in de praktijk worden gebracht?

Sinds vorig jaar staan er gekleurde pilaren op de universiteitscampus. Met deze ‘Act of Kindness Pillars’ wordt eenzaamheid bij studenten tegengegaan.

Studying abroad and going on an exchange is a great way to broaden your horizons and explore new places, cultures, and fields of study. In addition to a full-semester exchange, there are many other possibilities such as a summer school or an internship. For example, Bart Geldermans, Public Administration…

A European team of astronomers has discovered the largest stellar black hole in the Milky Way. It is more than thirty times as massive as our sun and is located in the constellation of Aquila, about two thousand light-years from Earth. The astronomers stumbled upon the black hole by chance while preparing…

The brightness peak of the ring around M87's supermassive black hole has shifted 30 degrees counterclockwise in a year. This is shown by new images released by the Event Horizon Telescope consortium.

Astronomers have measured the mass of a dormant, supermassive black hole in the early universe for the first time. Thanks to a combination of the James Webb Space Telescope and a natural cosmic magnifying glass, researchers were able to weigh the black hole directly based on its gravity.

An international team of astronomers led by Dutch scientist Martijn Oei has discovered the largest pair of jets from a black hole ever seen. The 'jumbojets' extend a combined length of 140 Milky Ways. The Leiden Observatory played a prominent role in this research. The publication will feature on the…

Grondstoffen werden vroeger over duizenden kilometers afstand vervoerd. Waarvoor werden ze geruild en waarom sloten mensen in West-Azië zich aan bij deze handelsnetwerken?

Een orang-oetan lacht niet gauw hard om een video waarin een soortgenoot dat ook doet. Een peuter doet het meer dan een volwassene, een Japanner weer iets minder. Chris Riddell leerde uit zijn vele experimenten ook dat geduld loont. Hij promoveert 16 september.

50 years ago Lauterbur published the basic principle of MRI. Sine then MRI has become more expensive. Professor Andrew Webb describes what is needed to make MRI available for everybody.

Drones zijn in korte tijd onderdeel geworden van het dagelijks leven. Ze worden gebruikt door hobbyisten, bedrijven, politie en defensie. Tegelijkertijd groeit de zorg dat dezelfde technologie ook kan worden ingezet door kwaadwillenden. Onderzoeker en promovendus Stijn Willem van 't Land zocht dit u…

From 16 to 20 June 2025, the Institute of Security and Global Affairs of Leiden University hosted the annual Summer School The European Union, the United Nations and Global Governance in The Hague. The programme brought together recent graduates, PhD students, and young professionals from a variety…

Last Friday, June 3rd, students, professionals and academics put their knowledge to the test during the Leiden Leadership Pubquiz/Leiden Leadership Summer Café. The pubquiz, hosted by Eduard Schmidt, touched upon public leadership in the news, posed statements about remarkable leadership research, and…

For many students, a summer school abroad is a fun and useful way to spend the summer. This year, because of the travel restrictions, many summer schools were held online. There was no less interest from students though. What is it like to study in a different country, but digitally? Or to travel abroad…

Bachelor's and master's students and PhD candidates came together from 10 to 13 July at Campus The Hague for the EUniWell Summer School ‘COVID-19: Impact on European health & well-being’. The participants attended lectures and workshops on the impact of the pandemic on public health. They also discussed…
