This not only produces beautiful images, but also provides more information about the enormous amounts of energy released around supermassive black holes in clusters. The astronomers,…

When a star gets too close to a supermassive black hole, it is torn apart by strong tidal forces in a tidal disruption event (TDE).

Professor Henk Schulte Nordholt was made a Knight of the Order of the Netherlands Lion on Friday 6 September 2019 for his services to the study of Indonesia. Mayor of Leiden, Henri Lenferink, presented him with his medal. This was at the end of a valedictory symposium for and a valedictory speech by…

Astronomer Henk Hoekstra has been appointed Professor Observational Cosmology at the Leiden Observatory with effect from 1 August.

The aim of the project is to contribute to the process of archive formation ongoing in Post-Apartheid South Africa through the inclusion of photographs that have been either unacknowledged or excised from the national canon.

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.

In this thesis new methodologies are developed for the detection and systematic study of radio sources in the early universe. This allows us to gain a deeper understanding of the formation and evolution of galaxies, the activity of supermassive black holes, and the final phase transition of our universe:…

On 3 December the Europa Institute organised a debate about the figure of Black Pete. The central theme of the debate was the role which the law can play in deciding the future of Black Pete.

They are often referred to as ‘The Oscars of the Natural Sciences’: the Breakthrough Prizes in Life Sciences, Fundamental Physics and Mathematics. This year, the prize for physics went to the Event Horizon Telescope team, which took the first-ever picture of a black hole. Four Leiden astronomers were…

Dr. Henk Schulte Nordholt, working at KITLV and LIAS, has been appointed extraordinary professor of Indonesian history for a five-year period.

With the passing of Henk Jan de Jonge on 16 April 2022, Leiden University has lost one of its most characteristic, learned and devoted professors.

Stars orbit black holes while jumping up and down. This is the prediction of a theoretical model developed by Leiden physicist Satish Kumar Saravanan, based on Einstein’s theory of relativity. He defends his PhD thesis on July 7th.

On August 18, 2022, Henk Bodewitz, distinguished Indologist and emeritus professor of Sanskrit at Leiden University, passed away in his hometown of Utrecht.

82 years ago Queen Wilhelmina fled to England. Henk te Velde tells about her on the Australian radio show 'Nightlife'.

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…

All kinds of reasons have been put forward for why plants apparently fail to make maximum use of the available light. None of these reasons can explain why after two billion years of evolution they are not black, like industrial photovoltaic solar cells. Are we missing something?

For the first time, astronomers have managed to take a photo of a supermassive black hole and its shadow. They used the Event Horizon Telescope (EHT), a worldwide network of eight radio telescopes that together form a virtual telescope the size of the earth. The news was presented in six press conferences…

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.

Older children more frequently link Black Pete with a black person. Both younger and older children think positively about him. This is the conclusion of a study conducted by Judi Mesman, Professor of Diversity in Parenting and Development.

All supermassive black holes in the centres of galaxies appear to have periods when they swallow matter from their close surroundings. But that is about as far as the similarities go. That's the conclusion reached by British and Dutch astronomers from their research with ultra-sensitive radio telescopes…

The first photo of a black hole and measuring anxiety in the brain... From 13 until 22 May we're serving a free slice of science with your pizza.

Two black holes, in close orbit around each other. Have they slowly drifted together, or did they emerge from two orbiting stars? Together with to colleagues form Amsterdam, Leiden astronomer Simon Portegies Zwart calculated that the second scenario is rather likely.

The faculty's research on the ancient rock art found in Jordan's Black Desert has recently been covered by several news and science websites.

We don’t understand how some materials become superconducting at relatively high temperatures. Leiden physicists have now found a surprising connection with auxiliary black holes. It enables us to use our knowledge of black holes on the mystery of high-temperature superconductivity. Publication in Nature…
