ALMA has observed stars like the Sun at a very early stage in their formation and found traces of methyl isocyanate - a chemical building block of life. This is the first ever detection of this prebiotic molecule towards solar-type protostars, the sort from which our Solar System evolved. The discovery…

China-watchers are still grappling with the wide-ranging implications of the Hong Kong national security law. Has Beijing really abrogated the legally-binding Sino-British Joint Declaration after just 23 of the agreed-upon 50 years?

Leiden University has partnerships in the local region, in the Netherlands, in Europe and with countries on almost all the world's continents. Students and researchers benefit from these partnerships, but society is also a beneficiary, says Rector Carel Stolker.

The solar system was formed approximately 4.56 billion years ago. Despite the numerous theories that have been developed over the years, the formation and evolution of the solar system still remain unclear.

An international team led by Leiden astronomers has taken the first-ever image of a young, Sun-like star accompanied by two giant exoplanets. The researchers used The European Southern Observatory’s Very Large Telescope for this, known as ESO’s VLT. Images of systems with multiple exoplanets are extremely…

As South Korean president Moon Jae-in prepares to leave office, North Korean leader Kim Jong Un has thanked him for trying to improve relations. Assistant Professor Christopher Green explains in the Calgary Sun what impact North Korea's gesture of goodwill might have.

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…

‘Take science communication more seriously.’ This is the message that Ivo van Vulpen, professor by special appointment in Science Communication in Physics, wants to convey during his inaugural lecture. At the moment, a lot of researchers look down their noses at this while it is extremely important…

No sitting in lecture halls, no coffee at the JuCa: Leiden Law School students will have to follow lectures and do exams from home for the time being. A huge transition.

Thousands of first-year students and hundreds of mentors kicked off the EL CID on Monday morning. This year for the first time, the introduction week of Leiden University and Leiden University of Applied Sciences was also open for students of Regional Training Centre mboRijnland and the Leiden Instrument…

The impact of global connections and the formation of the Roman Empire (ca. 200-30 BC)

The fourth conference of Isis Studies was organised by Liège college and has now been published by Laurent Bricault and Miguel John Versluys.

Using the James Webb Space Telescope, an international team of researchers, including Leiden Professor of Molecular Astrophysics Ewine van Dishoeck, has discovered a palette of hydrocarbons in a planet-forming disc around a young, low-mass star. The results confirm that discs around very lightweight…

From chilling on the beach to a speech by the mayor. HOPweek is a speedy way for hundreds of ‘Leiden’ students who are going to be studying in The Hague to get to know each other. Many of them come from abroad. ‘I actually dare to cycle here.’

Astronomers led by Leiden PhD candidate Richelle van Capelleveen have, for the first time, discovered an exoplanet that has carved a bright gap in the protoplanetary disc around its star. This rare observation provides new insights into how young planets shape their surroundings.

Research using the ALMA telescope by scientists including Leiden's John Tobin and Steven Bos has produced the first images of the water snow line within a protoplanetary disc. Publication in Nature on 14 July.

The recognition that there may be more, so-called allosteric binding sites on a given receptor has also fueled our synthetic efforts. Over the last few years we have focused on many drug targets (adenosine A1, A2A and A3 receptors, the mGlu2 receptor and a classic ‘anti-target’, the hERG channel) to…

Rainbow flags, funky sounds and drag queen Petty Libel: the very first Canal Pride Leiden has become reality. Leiden University joined the parade with a packed and buzzing boat. ‘The Leideners were really supportive and gave us a great response.’
