A group of astronomers led by Leiden PhD student Sebastian Zieba has discovered using the James Webb Space Telescope (JWST) that the rocky exoplanet TRAPPIST-1 c has a thin atmosphere. Although the planet is nearly identical to Venus in size and temperature, and was expected to have a thick atmosphere,…

Former PhD student Cameron Mackie will been awarded not one, but two dissertation prizes for his thesis on the aromatic universe. His work could provide us with a virtual sniff of space. ‘These molecules in space likely smell like a big charcoal grill!’

They hurtle along at over a thousand kilometres per second: the fastest stars in the Milky Way. PhD candidate Fraser Evans conducted research into these elusive hypervelocity stars and discovered that they have a lot to teach us, about black holes and supernovae, for example.

Providers of telephone, internet or data centers can be seen as companies of vital importance because of their national importance. This comes as no surprise. In the Netherlands, additional legislation was deemed necessary to protect national security and a legislative proposal was presented in April…

After 25 years, this December will finally see the launch of the long-awaited James Webb space telescope (JWST). Leiden astronomers are watching with great excitement: not only were they involved in the construction of important instruments on board, but the telescope will also reveal many new secrets…

Court cases that get out of hand are enacted again and again, according to PhD candidate Tessa de Zeeuw. De Zeeuw: ‘Even if the court comes to the correct judgement, from a legal point of view, the issues that appear in a case such as that of Lucia de Berk continue to

Leiden University is developping a major, new university premises at Spui, in the city centre of The Hague. The building, a former department store, will provide space for some 3,000 university students and staff. Construction starts early in 2023. The doors of the Spui Building are planned to open…

Who shall be responsible or liable when damage is caused by Global Navigation Satellite System (GNSS)? Is it fair enough to force a GNSS provider to bear the burden of compensation given GNSS open signals are provided free of charge? And are current international laws adequate to deal with those questions?…

Student Marieke van der Heijden wandelt wekelijks met senioren bij het project Leren met de Stad. Zij doet onderzoek naar sociale cohesie in de wijk De Kooi.

Dark matter represents around eighty per cent of the total mass in the Universe. Yet, we still don't really know what it's made of. Astronomer Pavel Mancera Piña is looking for answers. With a Veni grant from NWO and the most advanced telescopes, such as the James Webb Space Telescope, he will investigate…

Discovering what is inside giant planets and their atmosphere, that is one of the goals of astronomer Yamila Miguel. With an ERC Consolidator Grant of 2 million euro, she will study giant planets both inside and outside our solar system. ‘We want to know more about how planetary systems are born, how…

How can you see something that’s invisible? Well, with Euclid! This future ESA telescope will map the structure of the Universe and teach us more about invisible dark matter and dark energy. Scientific coordinator of Euclid and Leiden astronomer Henk Hoekstra explains how this works.

From the effects of hormone fluctuations in women via the interior structure of giant planets to the prehistory of the languages: six Leiden researchers have been awarded a Consolidator Grant by the European Research Council.

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…

Patients and healthcare providers use Remote Patient Management platforms to exchange information with each other. New methods like this are desperately needed to future-proof our healthcare systems. Professor Maaike Kleinsmann is working to scale up these systems and implement them nationwide.

NASA’s telescope SOFIA has provided a new glimpse of the chemistry in the inner region surrounding massive young stars where future planets could begin to form. Leiden PhD candidate Andrew Barr writes about it in the Astrophysical Journal. The scientists found massive quantities of water and organic…

An international team of astronomers led by scientists from Leiden Observatory has for the first time characterised a dust disk surrounding a young super-Jupiter, which is either a giant planet or brown dwarf. They detected infrared emission from the disk which might indicate that moons may have formed.…

A team of Leiden astronomers used the latest set of data from ESA’s Gaia mission to look for high-velocity stars being kicked out of the Milky Way, but were surprised to find stars instead sprinting inwards – perhaps from another galaxy.
