It's one of the big cosmology debates: the universe is expanding, but how fast exactly? Two available measurements yield different results. Leiden physicist David Harvey adapted an independent third measurement method, using the light warping properties of galaxies predicted by Einstein. He published…

The two instruments of ESA's space telescope Euclid have taken their first test images. The first images indicate that the space telescope will achieve the scientific goals for which it was designed - and possibly much more. Euclid will create a 3D map of a third of the sky, allowing scientists to study…

An international team of astronomers, including Leiden PhD student Elia Pizzati, has observed several ancient quasars that, surprisingly, appear to be floating alone in the early universe (less than a billion years after the Big Bang). Until now, astronomers, based on models, assumed that quasars are…

Four researchers from Leiden University have been awarded prestigious Vici grants the Dutch Research Council (NWO) has announced. The honoured applications are from researchers at the Faculty of Social and Behavioural Sciences, Leiden Observatory, the LUMC and the Faculty of Archaeology.

At the Faculty of Archaeology, we investigate the development of human societies worldwide, from the earliest beginnings to modern times. We also study the heritage of mankind, which evokes this deep history, and which connects with, and informs, contemporary society.

Geheime diensten en criminelen kunnen inbreken in slimme apparaten, door slechte beveiliging. De markt lost het niet op: bedrijven willen gadgets verkopen, burgers doen ook weinig. NRC sprak hierover met Bibi van den Berg.

The researchers gave an overview of the research which will be conducted in the Living Lab in the coming year. The Living Lab is located in the BioScience Park in…

Not only dark matter, but also ordinary matter and dark energy are tracked in the largest ever cosmological computer simulation ever. In the FLAMINGO simulations, you can see virtual galaxies and clusters of galaxies emerging over the course of billions of years. This is no easy task: with more than…

This research project is funded by a subsidy from Instituut Gak.

A glittering visualisation of dark matter by Dutch artist Thijs Biersteker is on display in the Science Gallery at Trinity College Dublin. The installation – ‘Dark Distortions’ – was inspired by Euclid, a forthcoming ESA mission to study the mysterious nature of dark matter. Leiden astronomer Henk Hoekstra…

A signal that is present both in the centre of our Milky Way and in distant places in the universe could reveal the origin of dark matter. This is what Leiden physicist Alexey Boyarsky concludes in an article in Physical Review Letters.

30 Years of Pale Blue Dot - 14 February 2020, Kaiserzaal, Old Observatory - The Pale Blue Dot Symposium is an event to celebrate the 30th anniversary of the iconic picture showing the Earth as a tiny speck in the vastness of space and to discuss its impact on humankind. At the end of the symposium,…

On Monday 27 September 2010 Spinoza prize winners Naomi Ellemers, Ineke Sluiter, Marijn Franx (Leiden) and Piet Gros (Utrecht) announced their plans for their €2.5 million prize money. This was during the official ceremony in The Hague, at which the outgoing Secretary of State for Education, Culture…

With the help of software that mimics a human brain, ESA’s Gaia satellite spotted six stars zipping at high speed from the centre of our Galaxy to its outskirts. This could provide key information about some of the most obscure regions of the Milky Way.

Using the Dutch-led Low Frequency Array (LOFAR) radio telescope, astronomers have discovered unusual radio waves coming from the nearby red dwarf star GJ1151. The radio waves bear the tell-tale signature of aurorae caused by an interaction between a star and its planet. The radio emission from a star-planet…

Disk formation around stars is an important factor in determining whether one or multiple stars evolve. But the big picture of star formation is still far from complete, says PhD researcher Nadia Murillo.

Eleven Leiden researchers have been awarded a Veni grant by the Dutch Research Council (NWO). The grant will enable them to develop their research ideas for a period of three years.

The European Research Council has awarded a Starting Grant to five early career scientists from Leiden University. They received funding up to 1.5 million euros to further expand on their research subject.

Social resilience and security has never been more important. Over the last 2 years, the COVID-19 pandemic has created a considerable disturbance to our personal and social lives. As a result, the general population reports more stress, loneliness and decreased quality of life. At the same time, there…

Why did 'character', 'habit', and 'virtue' serve as key terms in late 19th and early 20th-century scholarly correspondences, biographies, and obituaries? Why did scholars around 1900 display so much interest in the working habits and character traits of what they called the 'scholarly self'?

Yesterday, the International Court of Justice (ICJ) issued a preliminary ruling in a case brought by Nicaragua against Germany.

In Green Bank, Virginia are some giant radio telescopes which astronomers use to study objects deep in space. Because these telescopes are built to capture very faint redio signals, the area around the observatory is officially a 'radio-quiet' zone, without WiFi, radio or Cell signal. Photographers…
