Henk Hoekstra and Alessandra Silvestri work on the astronomy and theoretical physics in the Euclid mission. These Dutch researchers are part of the mission.

The first full-colour images of the cosmos from ESA's space telescope Euclid were presented today. Never before has a telescope been able to take such crystal-clear astronomical images of such a large part of the sky and so far into the deep universe. The five images illustrate Euclid's full potential;…

During the second episode of this Leiden Law podcast, hosts Juli Wentholt and Ishana Badhai will talk with Tanja Masson-Zwaan about the latest developments in Space Law.

‘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…

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.

Students on the Adv. LL.M. Air and Space Law reacted quickly to the news of Ukrainians fleeing the war in Ukraine to neighbouring countries. Filip Draba, who is from Poland, collected donations from the class and, together with additional contributions from family and friends in Poland, he amassed €…

The shock wave triggered by one of the five galaxies making up the iconic Stephan’s Quintet appears to be less disruptive than previously thought, with the shock likely being cushioned by dust particles in the surrounding gas. This is according to the analysis of the first scientific observations of…

The year 2023 saw the earthquake in Turkey and Syria, the Wagner Group rebellion and wildfires and floods as all the weather records were smashed. Our most-read stories were about the climate crisis and the elections: here’s the list.

The Rein Dool painting depicting board members of Leiden University will be moving soon to the Reception Room in the Academy Building, where more people will be able to see it.

Many study programmes offer the opportunity to do an internship or research project, either as a compulsory part of the curriculum or to earn elective credits.

Although there is considerable evidence that nature in the city is beneficial to both people and animals, we still do not have an overall picture of those benefits. To rectify that, a Leiden PhD candidate and a student – armed with a cargo bike – are using The Hague as a life-size laboratory.

More papers, more grants, more students: constant growth is still the gold standard at universities. Neuroscientists Anne Urai and Claire Kelly argue that this mentality obstructs us in resolving such complex societal problems as the climate crisis. Their alternative? The university as a doughnut.

Over the past few months, Urban Studies students have been helping to think about the realisation of the Humanities Campus. To test their knowledge in practice, the future urban specialists gave advice on several different aspects, including thermal energy storage and the new central campus building…

In this 'Educatip's column, psychology teachers share their key insights about work. This time: course coordinator Evelien Broekhof received support from teaching assistant Vincent during the last term. ‘I have more room in my schedule now that I don't have to do everything alone anymore.’

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.

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.

The European Research Council (ERC) has awarded an Advanced Grant to six Leiden researchers. It awards these significant grants to established principal investigators for ground-breaking, high-risk research.

While investigating 16 years of images of young stars from a retired astronomical camera, Leiden master's student Sam de Regt discovered that two of those stars were still enveloped in birth clouds. Never before has anyone captured these two stars in so much detail. He publishes his data-cleaning method…

When deciding what to study you undoubtedly read a lot of information about your study programme. Leiden University employs various systems to provide information about programmes and courses and to facilitate communication between lecturers and students.

Minuscule elementary particles from space colliding with Earth can give us an insight into the distant objects they come from. But first, you need to know how to catch them. With a Vidi grant from NWO, researcher Sjoert van Velzen will 'hunt' for neutrinos coming from exploding black holes.

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…

In summer 2018 classical archaeologist Hanna Stöger passed away. At that moment she was in the midst of several cutting-edge research projects on the use of space in the Roman city of Ostia. To make sure that her groundbreaking work would not go unpublished, long-time colleagues Hans Kamermans and Bouke…

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…

What if I completely changed everything? A subject without lectures or exams, where the right answer is not important and where students work with their hands. With this idea, Michiel Brentjens reformed the course Radioastronomy. His students are so enthusiastic about this approach that they nominated…
