Protostars, data science, and the James Webb Space Telescope—Adriaan Janssen’s curiosity knows no bounds. As a double bachelor’s student in Physics and Astronomy, he has truly found his calling, underscored by his nomination for the title of Leiden Science Young Talent 2024.

Planets existing in other solar systems contain invaluable information about the origin of planets and life. PhD candidate Yapeng Zhang has studied their atmospheres by looking at their smallest parts: isotopes. With her research she hopes to discover what makes our own solar system unique.

With his clever measuring methods Ignas Snellen – together with his team – was the first to detect carbon monoxide in the atmosphere of exoplanets. For his pioneering work the Leiden astrophysicist has been awarded the Spinoza Prize, the highest academic honour in the Netherlands. The prize of 2.5 million…

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.

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?

They hurtle along at over a thousand kilometres per second: the fastest stars in the Milky Way. PhD candidate Fraser Evans conducted research into these elusive hypervelocity stars and discovered that they have a lot to teach us, about black holes and supernovae, for example.

Three fundamental research projects at Leiden in physics, chemistry and medical science have received funding from the Dutch Research Council (NWO). They involve research on magnetic fields in the universe, the role of myeloid cells in cancer immunotherapy and the evolution of ancient proteins.

There are countless ways to meet new people, at your own study programme and faculty, or elsewhere within the university.

From telescopes to science fiction: in just one semester, students with no background in physics or astronomy get to explore the universe. The first group of students started last month in the new minor Our Universe.

Exploring the largest structures in the universe by looking at the tiniest particles? Lydia Stofanova, PhD candidate at Leiden Observatory and SRON Netherlands Institute for Space Research, dives into this intricate connection. In her PhD research, she explored how elements like oxygen influence the…

The university was a gift from William of Orange to the people of Leiden for their courageous resistance to the Spanish. We’ve all heard the story of the university’s foundation. But its foundation was also a success story for two friends.

It was the Night of Discoveries on Saturday 16 September: a summer encounter between art and science. Leiden researchers from various disciplines inspired the public with their quest to understand our world.

For the first time, we’re seeing what Euclid sees. The telescope’s initial observations have provided a wealth of new information about our universe. But according to cosmologist Alessandra Silvestri, this is just the beginning. The research helps us gain a deeper understanding of the past, present,…

Lara Ummels came from Maastricht to study law in Leiden, and never left. She recently joined the board of the 3 October Association.

What should our education and research look like in 2027? How can we make the university more sustainable and achieve greater impact? The new Strategic Plan will set the direction for the coming years, and the Executive Board wants students and staff to provide as much input as possible. Would you like…
