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.

‘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…

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…

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…

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.

On Thursday 19 June, the sun-drenched garden of the Huizinga Building was the setting for the Education Market. Over snacks and drinks, colleagues inspired each other with educational innovations.

Eight early-career researchers from around the world have been awarded a 51 Pegasi b Fellowship – a prestigious opportunity for astronomers. Julia Santos, a PhD candidate at Leiden Observatory, is one of them. We asked her four questions about this remarkable fellowship.

Eight university vegetable patches will soon join the display at the Hortus botanicus. The sun shone down on almost 40 enthusiastic students and staff as they started work on the new Community Garden there earlier this month.

The South Cluster - the former Van Wijkplaats/Van Eyckhof on Witte Singel - is currently undergoing an impressive transformation. On 25 October, more than 100 enthusiastic colleagues witnessed the progress of the renovation during a series of tours of the building.

On 19 June, the grounds of the Kamerlingh Onnes Building were transformed into LAWLANDS! It had everything: sun, music, science, beach, games, quizzes and, above all, an enthusiastic audience of staff and students.

The Middle East has a rich literary tradition, which is steadily gaining a foothold in the West. Modern literary works deal with contemporary issues, such as the legacy of colonialism, the struggles between traditionalism and modernity, the place of women in society and the war in Israel/Palestine.

All persons making use of Leiden University buildings and grounds must comply with the general University house rules. These are listed in the Regulations on the Use of University Buildings, Grounds and Other Facilities, and are intended to guarantee order and safety for guests and staff alike.

Researchers using NASA’s James Webb Space Telescope may have detected atmospheric gases surrounding 55 Cancri e, a hot rocky exoplanet 41 light-years from Earth. This is the best evidence to date for the existence of any rocky planet atmosphere outside our solar system.

Hak, lawyer, international imagery law lecturer, and adjunct associate professor, talks about his PhD research on the use of images in international criminal prosecutions. He was a public prosecutor in Canada for over 30 years and dealt primarily with the prosecution of homicides and other major cri…

An international team of astronomers has revealed the first 'chemical profile' of an exoplanet's atmosphere. The team, including Leiden astronomer Yamila Miguel and provenda Amy Louca, made the profile using so-called Early Release Science data from the James Webb Space Telescope. The results have been…
