Today, ESA’s Gaia mission releases its new treasure trove of data about our home galaxy. Astronomers, led by the Leiden astronomer Anthony Brown, describe strange ‘starquakes’, stellar DNA, asymmetric motions and other fascinating insights in this most detailed Milky Way survey to date.

Professor Ignas Snellen has developed an online platform where exoplanet researchers can post videos about their work: exoplanet-talks.org. ‘For young researchers in particular it’s a way to bring their research to people’s attention.’

Four different astronomical societies are active in the Old Observatory. We are very proud of the commitment these associations show to organize activities.

The Leidse Weer en Sterrenkunde Kring (LWSK) is a society of amateurs interested in astronomy, space travel and meteorology. The association organises a monthly lecture on a fascinating subject, given by an expert in the field.

Leiden University finds it very important that you choose the study programme that is right for you. That’s why we offer so-called matching activities, to help you in your decision.

An international team of researchers led by Alice Booth (Leiden University, the Netherlands) have discovered methanol in the warm part of a planet-forming disk. The methanol cannot have been produced there and must have originated in the cold gas clouds from which the star and the disk formed. Thus,…

A team of Leiden astronomers has managed to calculate the first 100 million years of the history of the Oort cloud in its entirety. Until now, only parts of the history had been studied separately. The cloud, with roughly 100 billion comet-like objects, forms an enormous shell at the edge of our solar…

With a special symposium at Museum Boerhaave, ESO celebrated its 60th anniversary on Monday, 26 September. More than 100 scientists, politicians and people from industry were present to look back on collaborations, milestones and discoveries. Leiden astrochemist Ewine van Dishoeck was one of the pre…

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…
