Many protoplanetary discs in which new planets are formed are much smaller than thought. Using the Atacama Large Millimeter/submillimeter Array (ALMA) scientists of the Leiden Observatory looked at 73 protoplanetary discs in the Lupus region.

A gold carpet welcomed students, staff and curious locals into Spui Campus on Monday 2 February. The V&D department store has been transformed into a unique open knowledge centre.

A team of scientists, including Leiden Astronomer Alice Booth, has discovered silicon monosulfide molecules in the dust disk around a young star. Such molecules indicate planet formation. The team made the discovery using the ALMA telescopes. This method provides an alternative when direct observation…

What is it like to participate in the Erasmus+ grant programme as a Master's student from Ukraine? Yevhenii Radchenko did an eight-month internship at Leiden University in 2018. Soon after, he returned as a PhD candidate. 'You have little to lose, but a lot to gain.'

During the Week Against Loneliness, we ask staff to (symbolically) open their doors, especially those such as lecturers and student advisers who work with students.

A degree in the Humanities provides a strong start in the labour market, according to research conducted among alumni who graduated between 2020 and 2024.

Astronomers led by Leiden PhD candidate Richelle van Capelleveen have, for the first time, discovered an exoplanet that has carved a bright gap in the protoplanetary disc around its star. This rare observation provides new insights into how young planets shape their surroundings.

With a single sample of water or soil, researches can analyse the DNA of everything that is living in that environment. During her research, PhD candidate Beilun Zhao discovered a way to analyse not only the kind of species, but also the age of the species in a water sample. The method showed its first…

Laura Kamsma (31) has been coordinating the International Office (IO) of FGGA for a few months now. An introduction to the ambitious Nijmegen native, who has set herself the goal of making the International Office more visible: 'Knock on our door if you have an internationalisation issue. Now you can…

Plants not only sense when they are touched, but they can also adapt to it. For example, by strengthening or defending themselves. But how do plants do this? The Green TE (Green Tissue Engineering) consortium has been granted a Gravitation grant of almost 23 million euros to investigate exactly this…

Oberon Janszen, alumnus Bestuurskunde, ging na zijn studie als stagiair bij de Inspectie der Rijksfinanciën aan de slag

De AIVD gebruikt omstreden hacksoftware van de Israëlische leverancier NSO Group, meldde de Volkskrant. In 2019 zou de telefoon van topcriminineel Ridouan Taghi er mee gehackt zijn.

Universiteiten moeten niet verbaasd zijn dat studenten ChatGPT gebruiken, schrijven de Leidse universitair docenten Femke Klaver en Alexander de Wit in Trouw. Want studenten reageren op efficiëntie en doelmatigheid. Hun suggestie: Leid studenten op om kritisch na te denken.

Bringing the community together, doing up the community centre or researching how to make gardens greener. Students now have a base in Leiden-Noord where they can work with local residents and partner organisations to make the city a better place to live. It was the official opening of ‘Learning with…

Inaugural lecture

The theme of the Heritage Open Days Leiden on 10 and 11 September is sustainability. At four University locations guides will talk about the history of the buildings and how they have been renovated. And there is a first: tours in sign language.

Ontdek je eigen gedrag en dat van anderen tijdens onze unieke teambuildingervaring, waar wetenschap, emoties en spelletjes samenkomen!

Could water be present in planet-forming disks before the formation of rocky planets? The James Webb Space Telescope may have found evidence for that. Webb has for the first time observed water in the inner disc around young star where at greater distance, giant planets have already formed. The 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…

Seksueel misbruik tussen broers en zussen kan ook na jaren nog grote impact op de familierelaties. Dat blijkt uit onderzoek van Sheila van Berkel, Iva Bicanic en Anja van der Voort, die slachtoffers met elkaar in gesprek brachten over hun ervaringen. ‘Ouders ontkenden of minimaliseerden het misbruik…

An international team of scientists, including Xander Tielens of Leiden Observatory, has used space telescope Hubble and the ALMA observatory to show that UV radiation from massive stars can prevent planets from forming. The researchers publish their findings on 1 March in the journal Science.
