The 'deepest and sharpest' image of the Universe to date: the first photos from the new James Webb space telescope yesterday mesmerised astronomers and the public alike. Leiden Professor of Molecular Astrophysics, Ewine van Dishoeck, spoke to various media outlets about the first images, which include…

The James Webb Space Telescope (JWST) allows us to look deeper into the universe than ever before. Not only does this provide a mass of data, but also stunning images. You can admire all of that in the Old Observatory's new exhibition: JWST Universe. Be amazed by the stunning images and learn more about…

After ten years and one day, Leiden Observatory has a new director. As of 1 September, Ignas Snellen will set the course for the astronomical institute. In this interview, you will get to know Ignas. Or at least a little. That is why we gave him five dilemmas and asked the people around him who he really…

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…

An internship or research project abroad is not only a fun and educational experience, it's also a great asset to your CV. As job markets are becoming increasingly international, employers tend to view international experience as a big advantage. Read more about how to arrange an internship or project…

An event where students from all honoursprograms meet, learn from each other and gain inspiration. That is the idea behind the Honours Conference, which took place at the end of February in the Old Observatory. The theme of the afternoon: why listening pays off.

A European team of astronomers has discovered the largest stellar black hole in the Milky Way. It is more than thirty times as massive as our sun and is located in the constellation of Aquila, about two thousand light-years from Earth. The astronomers stumbled upon the black hole by chance while preparing…

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.

Using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, researchers at Leiden Observatory in the Netherlands have for the first time detected dimethyl ether in a planet-forming disc. With nine atoms, this is the largest molecule identified in such a disc to date. It is also a precursor…

An international team of scientists, including Xander Tielens of Leiden Observatory, has used space telescope Hubble and the ALMA observatory to show that UV radiation from massive stars can prevent planets from forming. The researchers publish their findings on 1 March in the journal Science.
