The focus of this thesis is how stars like our Sun and planets like Jupiter, Saturn, and Earth are formed.

We are living in an information era where the amount of image and video data increases exponentially.

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…

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.

Reproducing past, present and future: colonial visions and experience in Asia in the residencies

Striga hermonthica, commonly known as witchweed, infests major cereal crops in Sub-Saharan Africa causing severe yield losses and threatening the livelihood of millions of resource poor farmers.

What will it be like to study at Leiden University in 2075? Ten surprising, artistic uni-visions could be brought to life. It’s up to you to vote for your favourite.

Junk news sites with unknown names such as Trendnieuws and Viraal Vandaag reach millions of Dutch people thanks to their Facebook pages. Messages from those pages are much more often shared and liked than messages from pages from well-known news media such as De Telegraaf, NOS and NU.nl. This is shown…

With the dramatic growth of the image data on the web, there is an increasing demand of the algorithms capable of understanding the visual information automatically.

About the event

In this thesis we explore machine and deep learning approaches that address keychallenges in high dimensional problem areas and also in improving accuracy in wellknown problems. In high dimensional contexts, we have focused on computational fluid dynamics (CFD) simulations.

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…

In 2018, the number of mobile phone users will reach about 4.9 billion. Assuming an average of 5 photos taken per day using the built-in cameras would result in about 9 trillion photos annually.

Professor Anne Meuwese is calling on governments to show more vulnerability when it comes to providing information about how they function.

Would you like Leiden University to be a more open workplace that recognizes and rewards all contributions, and an institution that creates and shares knowledge more freely with society?

Since the start of the Green Office, several projects have been initiated to increase awareness amongst staff & students and to make the university more sustainable. Read all about our current projects here.

How can we work together to create a safe study and learning environment and offer students the support that they need? The Vision on Student Well-Being outlines the University’s plans to promote student well-being in the coming years.

In 1933, Maria Ulfah Santoso was the first Indonesian women to earn a law degree. During her studies in Leiden University she became involved with Indonesia;s nationalist movement. She went on to be Indonesia's Social Minister, as the first female cabinet member. In this article, historian Wildan Sena…

The Old Observatory has a rich history. On this page you will find a short version of the history that took place in the observatory.

Leiden University has participated in an international study carried out by the CARMENES consortium, which has discovered two small, terrestrial planets around Teegarden’s Star. The planets have masses similar to Earth and their temperatures could be mild enough to sustain liquid water on their surf…

The SAILS conference The Future of AI is Here (and Guess What … it’s Human) brought together researchers and policy makers to discuss the important issues in the area of artificial intelligence (AI). Where are the opportunities and what are the dangers?

By carrying out fundamental research and providing excellent education, universities become a breeding ground for innovation and entrepreneurship.

This thesis investigates the application of deep learning techniques in image analysis across various domains, focusing on four main themes: feature extraction, classification, segmentation, and integration, demonstrating the transformative potential of these technologies.

We explored how to morphologically classify well-resolved jetted radio-loud active galactic nuclei (RLAGN) in the LOw Frequency Array (LOFAR) Two-metre Sky Survey (LoTSS) using machine learning.

Stars orbit black holes while jumping up and down. This is the prediction of a theoretical model developed by Leiden physicist Satish Kumar Saravanan, based on Einstein’s theory of relativity. He defends his PhD thesis on July 7th.

The Old Observatory houses four historical telescopes. On this page you can learn more about them.

SciSTIP was established on 1 April 2014 as part of the DSI-NRF Centres of Excellence Programme funded by the South Africa’s National Research Foundation (https://www.nrf.ac.za/). SciSTIP is hosted by the Centre for Research on Evaluation, Science and Technology (CREST) at Stellenbosch University and…

The physics of black holes appears to be as far removed from the physics of electrons in metals as it can be.
