Corrie Bakels is known as one of the founders of bio-archaeology in the Netherlands. One of her former students, Dr Marco Langbroek, active in astronomy, made a request to the International Astronomic Union to name a recently discovered asteroid after her. Hearing the news, Bakels was astounded. 'My…

Nienke van der Marel has been awarded the New Horizons Prize in physics for her pioneering research on planet formation. This prize is given to young, promising researchers in physics or mathematics. The astronomer and her colleagues found the first observational evidence for 'dust traps' in disks around…

The year 2023 saw the earthquake in Turkey and Syria, the Wagner Group rebellion and wildfires and floods as all the weather records were smashed. Our most-read stories were about the climate crisis and the elections: here’s the list.

It’s about much more than learning how to write a readable piece or give a presentation that doesn’t send the audience to sleep. The intensive Science Communication Summer School gives young scientists the chance to really make contact with the public.

You can make some astounding images using just a box with a hole. Inspired by the celebration of Leiden as the European City of Science, Professor Matthew Kenworthy left several pinhole cameras across the Observatory over the course of 2021. This is how the simplest devices may uncover the greatest…

Researchers from Leiden University analysed almost 30 years of communication on astrobiology. News articles proved most speculative, especially via quotes from scientists. Especially exoplanet research is often accompanied by high expectations about extraterrestrial life, they write in PLOS One.

From research on stellar winds to sign language: an impressive seven researchers from Leiden University will receive a prestigious Vici grant from the Dutch Research Council (NWO).

On January 1st Jasper Knoester started as our new dean. How is he finding it? What kinds of things is he doing and what does his day look like? In each newsletter Jasper gives a peek into his life as dean.

A beautiful speech by vice-dean Bart de Smit, a mini-lecture on exoplanets and the presentation of three faculty awards. That's how we started the new year at the faculty.

Five projects with a lead applicant from Leiden will receive an Open Science Fund grant from the Dutch Research Council (NWO).

How do we deal with large sources of greenhouse gases? Do schools provide a socially-inclusive environment for all children? And how can we protect Earth’s nature? These questions have two things in common: they are complex global challenges, and data can help answer them. Mitra Baratchi is computer…

The Plants & Planets exhibition brings two worlds together in a dazzling mix of science, nature and art. It opens at Old Observatory Leiden and Hortus botanicus on 7 February.

It doesn't happen every day that the research project of a first-year bachelor’s student results in a scientific publication. And not only that, but as first author and on the cover of a leading physics journal. ‘We have given our lab education a thorough overhaul and it is paying off.’

Anthropologist Rodrigo Ochigame studies how AI is changing the practice of scientific research. From astrophysics to mathematics to climate science, they find that the adoption of new AI models is raising questions about what counts as reliable scientific evidence.

Jasper Knoester is the dean of the Faculty of Science. Normally Jasper looks back on a day in his life, but in the last newsletter of the year he does it a little differently....
