With a combination of incidental sunshine, torrential rain, and wind chills, weather conditions were not ideal for a hiking excursion. Even so, last Saturday, honours students braved a trek across an estate and a golf club in Wassenaar to learn about the relationship between gardens and nature. From…

Tjerk Oosterkamp of the Leiden Institute of Physics managed to do the first-ever measurement of gravity on a tiny particle - just 0.43 milligrams - where the quantum regime starts. He explains in Physics World why this is so challenging.

Leiden University will confer an honorary doctorate on astrophysicist Sara Seager for her work on exoplanets.

With a trip through the Netherlands, the preparations for the graduation of the Master Cyber Security had already started weeks ago. The apotheosis took place on Thursday, the 11th of February. A report of a digital graduation ceremony.

Last Thursday, March 6, Sabine Luning passed away after an illness of more than six months. Sabine was an inspiring teacher who enthused generations of anthropology students with both the theoretical side of social science and the practice of intensive fieldwork. As a researcher, she produced innovative…

How can we supply the growing world population with sustainable energy? At Laurens College in Rotterdam, Prof. Marc Koper speaks with the students about the crucial role of chemistry in the energy transition. Guest classes like this are a good way for school students to learn about the academic world,…

How is Young Star Renske Donkers doing now? Early this year she was the second person ever to win the Young Star Award for the best bachelor student. After her bachelor Molecular Science & Technology, Renske is now busy with her master Chemical Process Engineering in Delft. ‘This award was a great boost…

A star does not just appear in the sky overnight. Its creation takes tens of thousands of years. Twenty years ago, astronomers took a picture of a star in its birth phase. The James Webb Space Telescope (JWST) could now capture that same star in much greater detail. This does not only provide beautiful…

The James Webb Space Telescope continues to surprise us with stunning pictures, but of what exactly? Astronomer Nienke van der Marel shows with three images how massive stars lead short but explosive lives.

During the summer, staff and students of the Faculty of Archaeology travel to all parts of the world, initiating or joining fieldwork projects. Read some of our students' stories here!

Jasper Knoester is the dean of the Faculty of Science. How is he doing, what exactly does he do and what does his day look like? In each newsletter, Jasper gives an insight into his life.

An international team of astronomers including Leiden professor Ewine van Dishoeck has observed the benzene molecule (C6H6) in a planet-forming disk around a young star for the first time. The observations tell us more about the forming of planets in this disc, like our own Earth. The scientists publish…

‘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…

Four female computer scientists share a common goal: to showcase the significant contributions of women in computer science and inspire their students. Together, they are organising this year’s Alice & Eve event, a one-day symposium dedicated to celebrating women in computer science. The event, scheduled…
