For the first time, astronomers have detected the presence of complex organic molecules, the building blocks of life, in a protoplanetary disc surrounding a young star. The discovery reaffirms that the conditions that spawned the Earth and Sun are not unique in the Universe. The results are published…

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.

Detecting planets during their formation stages is crucial for understanding the history and diversity of fully developed planetary systems like our own. However, observing young planets directly is challenging because they are often deeply embedded within their host protoplanetary discs, rich in gas…

Although migration and integration have become important concepts today as a result of globalization, migration movements, integration, and multiculturalism have always been part of the history of Europe. Few people realize how many ethnic groups participated in migration within Europe or into Europe…

An international team of astronomers, including astronomers from Leiden University, has found the missing link in the path taken by water through star-forming clouds and young stars to comets and planets. They did so with the help of the ALMA observatory in Chile. The researchers published their findings…

Three Leiden astronomers have shown that some asteroids that are considered harmless for now, can collide with Earth in the future. They did their research with the help of an artificial neural network. The results have been accepted for publication in the journal Astronomy & Astrophysics.

The European Research Council has awarded an Advanced Grant to Prof. dr. Maarten E.R.G.N. Jansen for the research project

Just like us, plants also produce growth hormones, and they also go through an ageing process. The study of the genes and mechanisms behind these processes is useful not only for crop breeding and agriculture, but also for medical research. That is the view held by Professor of Plant Developmental Genetics…

The ALMA Local Expertise Group (Allegro) is located in the Leiden Observatory (Sterrewacht). Professor Ewine van Dishoeck: ‘The Netherlands has played an important role in establishing ALMA. Thanks to this subsidy, we can now reap the scientific benefits.'

As we are working very hard to make our University more green, it is of upmost importance that you join us in our battle and start increasing the local biodiversity from your own house!

Astronomers have used data from the European Gaia Space Telescope to discover 55 high-speed stars launched from the young star cluster R136 in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. This increases tenfold the number of known “runaway stars” in this region. The team of astronomers,…

Leiden PhD student Xuequan Zhou has designed a new promising molecule that efficiently kills cancer cells, but does not harm healthy tissue. The trick: the drug is only active when irradiated with light. Zhou’s new compound does this extra efficiently by cleverly self-organising into nanoparticles.…
