In the disk surrounding the young star WISPIT 2, not one but two planets are taking shape. Leiden PhD candidate Richelle van Capelleveen played a key role in this discovery, providing a rare glimpse into the early stages of planetary system formation.

The design for the METIS instrument for the Extremely Large Telescope (ELT) is final. The European Southern Observatory (ESO) has given the green light for production of all parts of the instrument. It is the first ELT instrument, designed and to be built under Dutch leadership, to formally pass the…

People can be easily mislead with graphs. But they don’t necessarily stay misled, the research shows.

Educators in European science museums sometimes think rather differently about the definition of an 'authentic' object. They think carefully about how they present those objects to teach visitors something or make them curious. This was shown in research by the Science Communication & Society department.…

Large pairs of planets thought to orbit each other without a star, do not exist after all. That conclude Leiden researchers, after extensive computer modelling and simulations. What the double dots seen by the James Webb Space Telescope are, remains a mystery.

Prof Harold Linnartz has been reappointed Director of Education of the bachelor and master programmes of Astronomy. The appointment is for a period of four years, until 1 October 2026.

Starting 1 September, three new Programme Directors will begin at FWN. Daan van der Es, Reinout van Weeren, and Amineh Ghorbani will each be responsible for a master's programme in our faculty.

Information provided by the Tax and Customs Administration is something that concerns every citizen. So it is not surprising that the Tax hotline receives around 10 million calls each year. The Benefits Affair emphasised the citizen’s perspective in communications with the Tax and Customs Administration.…

Why is water wet? What is ADHD? In De Hoe?Zo! Show, curious 9-and-10-year-olds get answers to their questions. PhD candidates take to the stage to demonstrate just how exciting science can be while enhancing their own communication skills at the same time.

Daniël Vredenberg did his master’s internship at the communications department of the Rijksvastgoedbedrijf. In this interview, he talks about his internship and the difference between actually working at an organisation, as he is currently doing, and doing an internship.

Tirza Cramwinckel, Assistant Professor in tax law, has won one of the 2023 Research Prizes awarded by the Praemium Erasmianum Foundation.

In July 2023, Leiden University conducted another phase of its ongoing archaeological collaboration with the Kalinago Territory in the Caribbean island of Dominica. Activities focused on mapping and assessing coastal sites impacted by climate stressors, undertaking knowledge-exchange sessions, and co-creating…

A team led by Leiden University in the Netherlands and the National Radio Astronomy Observatory have, for the first time, robustly detected semi-heavy water ice around a young sunlike star. In this ice, some of the ordinary hydrogen atoms have been replaced by deuterium, a heavier variant of hydroge…

Astronomers have captured a new deep field of Pandora's Cluster (Abell 2744) with the James Webb Space Telescope. The images show never-before-seen details. The results are described in four scientific papers. Leiden astronomers Marijn Franx and Mariska Kriek collaborated on the study. 'This opens a…

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…

Cosine Marco Beijersbergen has been appointed as one of the distinguished 62 fellows of the Netherlands Academy of Engineering (NAE). With these fellows, the NAE emphasises the importance of technological innovation for sustainable social change. The inauguration is on 13 November.

Aline Vidotto has been appointed professor of Stellar and Planetary Astrophysics at the Observatory from 1 February. Vidotto has been with the university for 3.5 years and for her, the appointment is ‘a milestone in her career.’

How do molecules originate and evolve in space? And how does that ultimately determine the chemical composition of planets and their atmospheres? The Dutch Astrochemistry Network (DANIII) receives 1.6 million euros from NWO to find out. A large group of Leiden astronomers and chemists is contributing:…

An international team of researchers led by astronomers from Leiden University (the Netherlands) has produced the first sharp radio maps of the universe at low frequencies. Thanks to a new calibration technique, they bypassed the disturbances of the Earth's ionosphere. They used the new method to study…

An international team of astronomers led by Matus Rybak (Leiden University) has proven, thanks to accidental double zoom, that millimetre radiation is generated close to the core of a supermassive black hole. Their findings have been accepted for publication in the journal Astronomy & Astrophysics.

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…

Protostars, data science, and the James Webb Space Telescope—Adriaan Janssen’s curiosity knows no bounds. As a double bachelor’s student in Physics and Astronomy, he has truly found his calling, underscored by his nomination for the title of Leiden Science Young Talent 2024.

A team of international researchers led by Tomas Stolker in the Netherlands has imaged a young gas giant exoplanet near a 12-million-year-old star. The planet is orbiting a star at which planet formation has finished, while the same-aged companion star still has a planet-forming disk. The researchers…
