Young suns and infant planets: Probing the origins of solar systems
Even though more than 4000 extra-solar planets are known today, only a small fraction of these has been captured in an image. To better understand the planet formation mechanisms in solar-like environments we started the Young Suns Exoplanet Survey (YSES).

Rubicon for ‘Artificial Sun’
Physicist Christopher Berg Smiet, who recently obtained his PhD in Leiden, has been awarded an NWO Rubicon. The grant allows him to conduct postdoctoral research for two years at the Princeton Plasma Physics Laboratory (PPPL) in the United States.

Marc Stevens and colleagues reveal weak spot in internet security
Marc Stevens, PhD student of Ronald Cramer, and colleagues have found a weak spot in internet security. As a consequence of this weak spot in the infrastructure of digital certificates forged certificates can be issued that can be fully trusted by the usual web browsers. The results have been presented…

Giant planet at large distance from sun-like star puzzles astronomers
A team of astronomers led by Dutch scientists have directly imaged a giant planet orbiting at a large distance around a sun-like star. Why this planet is so massive, and how it got to be there, is still a mystery. The researchers will publish their findings in the journal Astronomy & Astrophysics.

Cheering for the sun at the Leiden Observatory
Staring into the clouds hoping for a glimpse of the sun, cheering in encouragement, video recordings: there was no shortage of things to do at the Leiden Observatory. More than 600 visitors witnessed the last, almost complete solar eclipse of the decade..

Is our water older than the sun? Astronomers find clue in ice around young star
A team led by Leiden University in the Netherlands and the National Radio Astronomy Observatory have, for the first time, robustly detected semi-heavy water ice around a young sunlike star. In this ice, some of the ordinary hydrogen atoms have been replaced by deuterium, a heavier variant of hydroge…

What are we defending? Steven Pinker on the core values of NATO and the Enlightenment
NATO not only safeguards our security and stability, but also defends Enlightenment principles, promoting prosperity, health and freedom. This is what eminent psychologist and thinker Steven Pinker argued to a packed Great Auditorium.

Protostellar jets and planet-forming disks: Witnessing the formation of Solar System analogues with interferometry
The focus of this thesis is how stars like our Sun and planets like Jupiter, Saturn, and Earth are formed.

Traces of building block of life found around infant suns
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…

‘The sun never sets on our university'
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.

Dynamics of the Oort Cloud and Formation of Interstellar Comets Santiago Torres Rodriguez
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.

Astronomers capture first-ever image of a multi-planet system around a Sun-like star
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…

‘The sun is dying out’ as a wake-up call for better science communication
‘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…

Room for everyone at a sun-drenched EL CID
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…

around young low-mass star differs fundamentally from one around sun-like star
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…

First ring-forming embedded planet discovered around a young sun-like star
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.

Allosterism
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…
