Canal Watch (De Grachtwacht), which has been cleaning canals since 2018, has received the Dutch Research Council (NWO) Communication Initiative Award.

We investigate the buildup of galaxies from various vantage points. The first two chapters focus on the stellar content of galaxies, especially the distribution of stellar masses at birth and potential variations therein in various galactic environments.

It has now been well established that shocks and turbulent motions in the intra-cluster medium (ICM) generated through cluster mergers can produce large-scale synchrotron emission.

Anyone who creates a page for a magazine, a PowerPoint presentation, a brochure, a poster or dreams up an idea for an infographic is faced with important questions:

The KNAW has rewarded 11 Leiden scientists for their commitment to science communication, by awarding them 10,000 euros each from the ‘Appreciated!’ fund.

The Astronomy and and High-Tech Innovation specialisation consists of 120 European Credit Transfer System (EC) points and includes an astronomy component (60 EC), mostly in the first year, and a High-Tech Innovation component, mostly in the second year (60 EC).

The Astronomy and Education specialisation enables you to connect your scientific experience in astronomy with the theory and practice of teaching in the classroom.

Leiden astronomer Tim de Zeeuw has been appointed Knight in the Order of the Dutch Lion. He received the distinction on 14 May to mark his departure as Director General of the ESO European Astronomy organisation. The celebration took place during the 2018 Dutch Astronomers Conference in Groningen.

She left Leiden after her PhD and now, 14 years later, she returns as Professor of Extragalactic Astronomy. Mariska Kriek investigates how galaxies originate and evolve. And she is eagerly awaiting the launch for the new James Webb telescope: ‘The coolest things we are going to find are those we’re…

He discovered how to determine the rotation and centre of our Milky Way, predicted where comets come from and laid the groundwork for radio astronomy: Leiden Professor of Astronomy Jan Hendrik Oort (1900 – 1992). Piet van der Kruit, whose PhD supervisor was Oort himself, has written a biography about…

The British astronomer and mathematician Edmond Halley was not, after all, the first to understand the cycle of the comet that now bears his name. This is shown by research conducted by, among others, Professor Simon Portegies Zwart. It was the monk Eilmer of Malmesbury who, as early as the 11th century,…

This PhD project investigates the impacts of recognition of sign languages on communication and instruction for deaf learners in primary schools in Uganda.

The Dutch-Japanese made DESHIMA instrument has passed its first practical tests when measuring the distances and ages of distant galaxies. The core of the instrument is a chip the size of two euro coins that measures 49 shades of far infrared light. The developers of the spectrometer publish the results…
