Even with state-of-the-art technology, it is almost impossible to see: a cosmic neutrino. Yet scientists have managed to image this particle with a deep-sea telescope. And that could help to better understand our universe. Leiden particle physicists collaborated on this ambitious project, published…

Leiden scientists and companies receive 1.37 million euros to develop technology for the Einstein Telescope. This underground telescope will measure gravitational waves and must therefore be extremely sensitive. To that end, the consortium conducts research on the damping of vibrations at temperatures…

Scientists have detected a neutrino with the highest energy ever measured. Leiden physicists Maarten de Jong and Dorothea Samtleben were involved in this project, which was widely covered in newspapers and online media last week.

Three Dutch-Belgian telescopes have started operating at the ESO La Silla Observatory in Chile. This so-called BlackGEM array will scan the southern sky to hunt for cosmic events that produce gravitational waves, such as mergers of neutron stars and black holes. Leiden astronomer Rudolf le Poole is…

Leiden Observatory has achieved a rare feat: two of its research teams have been awarded prestigious ALMA Large Programmes, allowing them to study how galaxies formed and evolved in the early Universe using cutting-edge telescope observations.

Houses, warehouses, wells, a mooring and even a stable. All of this can be seen on the oldest known map of the island of Dejima acquired by Leiden University Libraries (UBL). The map provides a highly detailed picture of a tiny living environment on the isolated island.

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:…

James Webb life’s building blocks

It was while wearing clogs at a Dutch theme park in Japan that Cindy Heijdra really got to know Japan. Over 20 years later, she is studying again: to be a primary school teacher.

From the birth of the universe to the molecules in a planet's atmosphere. The first five pictures from the James Webb Space Telescope (JWST) show the enormous range in which the space telescope can operate. Ewine van Dishoeck, professor of molecular astrophysics, took a look at the first images Tuesday…

A star does not just appear in the sky overnight. Its creation takes tens of thousands of years. Twenty years ago, astronomers took a picture of a star in its birth phase. The James Webb Space Telescope (JWST) could now capture that same star in much greater detail. This does not only provide beautiful…

The highly successful deep-sea telescope KM3NeT can now expand both its size and scope.
