A team of Leiden astronomers has managed to calculate the first 100 million years of the history of the Oort cloud in its entirety. Until now, only parts of the history had been studied separately. The cloud, with roughly 100 billion comet-like objects, forms an enormous shell at the edge of our solar…

How do people vote? How rational are voting choices? How much do external factor weigh in? In this article social scientis provide some background.

Disk formation around stars is an important factor in determining whether one or multiple stars evolve. But the big picture of star formation is still far from complete, says PhD researcher Nadia Murillo.

In 2018, the Ministry of Education, Culture and Science (OCW) is celebrating its 100-year existence. To commemorate this occasion, policy historian Pieter Slaman conducted a comprehensive survey of the ministry. We now look back on 5 crucial moments.

Just like every other organism on Earth, plants’ ultimate goal is to survive and reproduce. In order to achieve this, they must make trade-offs between where and how to allocate their finite set of resources. Whether they put their resources and energy into their growth, reproduction or maintenance,…

Rachel Schats has been a familiar face at the Faculty of Archaeology since she started her bachelor’s in Archaeology in 2005. Now she is an assistant professor, working on her Veni project on malaria in the Middle Ages. ‘I have included in this project so many skeletal collections that no one has ever…

A night sky of more than 40 petabytes in size, simulating young star clusters and understanding how the body inhibits viruses: three Leiden projects have received computing time on one of the national computer systems.

‘I got into Nature last year, I was nominated for a faculty teaching award and my kids don’t care. But if your simulations get on The Big Bang Theory then that’s something!’ says Huib van Langevelde.

Fantastic plants, dizzying patterns and pulsating sounds: researchers from Leiden are going to study the effects of a simulated psychedelic trip on the mind and body at Lowlands Festival. Why might this be interesting for therapies?

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…

One unravels the origin of the largest black holes in the universe, the other investigates the influence of stellar wind on the atmosphere of exoplanets. Both Elena Maria Rossi and Aline Vidotto receive a Vici grant for their research into the mysteries of the universe. ‘I have no idea yet how we can…

An international team of astronomers, with researchers at Leiden Observatory playing a leading role, has mapped the fuel for galaxy formation in the iconic Hubble Ultra Deep Field. The results of the research have been accepted for publication in The Astrophysical Journal.

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.

Marlien van Mever delved into the analysis of tiny samples, cerebrospinal fluid from transgenic mouse models for example. She validated methods that can now be used to study brain diseases such as migraine and epilepsy. Van Mever will receive her PhD on 14 June.

For centuries, astronomers have studied the universe by collecting light signals. Since 2015, the confirmation of an important prediction of Einstein allows us to explore the universe in a new way: through gravitational wave radiation. Astronomy PhD candidate Valeriya Korol proposes to use these gravitational…

Physicists propose the existence of sterile neutrinos that would explain three big mysteries in nature. To actually find them in particle accelerators, researchers need to know how they are produced and how they decay. PhD candidate Kyrylo Bondarenko has made predictions about this, which are currently…

Professor Leo Lucassen often adds his voice to the public debate on his specialist field. If there is talk of a 'flood of migration', he feels compelled to give the issue some historical perspective. 'Concerned? Yes, I am.'

Bart Barendregt, Ratna Saptari, and Annemarie Samuels co-organised a two-day workshop on

Simulations of galaxy formation provide much more information about galaxies than a telescope. Simulations have been improving significantly in recent years. Astronomer Evgenii Chaikin made such a significant contribution to this field that he graduated with honours on February 27th.

On November 21, theoretical physicist Juan Maldacena gives the Ehrenfest Colloquium. Maldacena is known worldwide as the inventor of AdS/CFT correspondence, which might be key to a theory of quantum gravity. Maldacena is winner of the prestigious Dirac Prize and the Breakthrough Prize in Fundamental…

For over a year now, the James Webb Telescope has been sending stunning images that exceed astronomers’ expectations. The photos are fascinating to see, but what exactly are we looking at? Assistant professor Melissa McClure explains.

This year's Nobel Prize in Physics goes to quantum physics research. The prize will be awarded on December 10 in Stockholm. Physicist Bas Hensen explains why this is important and how his research in Leiden relates to it.

More people seeking asylum, overcrowded asylum accommodation and asylum procedures that take years because of a lack of capacity. The current government wants to declare an asylum crisis but what is that exactly and can they just do that?

Physicists understand little about quantum matter, which is a building block of future quantum computers. Theorists have now discovered that black holes with ‘dreadlocks’ harbor a similarly exotic order pattern, which makes calculations on quantum matter easier. Publication in Physical Review Letter…

Together. If we look back on the corona crisis some time from now, that will have been the keyword in the political communication, says Arco Timmermans. Having allies is imperative, especially in these times.
