The energy system is at the heart of two of the greatest challenges of the 21st century: decreasing CO2 emissions to meet the ambitions of the Paris agreement while fulfilling the growing energy demand associated with the economic aspirations of a growing world population.

In September 2023 Social Justice Research, a journal from Springer Nature, published a ‘Special Issue on Veteran Reflections’. Eight ‘veterans’ analysed the current status of justice research and suggested new directions and refinements. Herman Steensma, guest member of the section Social, Economic…

The project seeks to explore the interplay of valuation and inequalities in science, using the interdisciplinary and planet-critical field of forest research as empirical case. It examines which/whose knowledge is recognised on what grounds, and how social dimensions like gender and geographical location…

Our current lifestyle is not sustainable, and we know it. Our carbon-based economy causes climate change, and our livestock threatens the rainforests. We also know what we ought to do to save the planet: decarbonize the economy and change our diet. However, too many people lack the moral motivation…

LUC's Liberal Arts and Sciences programme is centered around these four Global Challenges: Peace & Justice, Sustainability, Diversity, and Prosperity.

High-quality education, a broad choice of bachelor’s and master’s programmes and personal support in two student cities. And that’s just for starters. Leiden University offers you the ideal basis for enjoying the time of your life and gives you a head start to a world-class career.

The Hague is the Netherlands’ fastest-growing student city, and has been Leiden University’s second location since 2010. In addition to housing the Netherlands’ ministries and government bodies, The Hague is the International City of Peace and Justice and is home to countless embassies, political…

Studying in The Hague can make a big difference. The Hague is proud to be known as the international city of peace, justice and security. The city is full of opportunity and is a fantastic student city.

With 8.9 million euros from the Danish National Research Foundation, Aarhus University and Leiden Observatory will establish the Center for Interstellar Catalysis. The centre is led by Aarhus professor Liv Hornekær and aims to find out how and when the building blocks of life formed in the Universe.…

Agricultural production is one of the most vulnerable sectors to climate change around the world, and poorer countries face significantly more difficulties than the developed world. Coffee is an agricultural commodity that most people enjoy but are oblivious to the climate-related challenges affecting…

Is there extra-terrestrial life out there? It now looks as though we can sketch out an answer to this enduring question. Leiden Observatory is helping to build new instruments to find the most promising exoplanets.

These podcast episodes were written for the Green Office’s Spring Podcast competition and miniseries 'Beyond the Safe Space', on the theme: the Planetary Boundaries, which took place between the months of March-May 2023.

Leiden Observatory is the astronomical institute of the Faculty of Science of Leiden University.

We are very excited to announce our Sustainability Series for 2023-2024. Each month an interactive workshop will be organised that discusses a specific theme of sustainability. Interested about sustainability? Do not hesitate to sign up to our events !

Below you will find a collection of books, other than those in the BLRN book series, to which members of BLRN have contributed.

World history, connectivity and material culture, edited by Martin Pitts and Miguel John Versluys. From Cambridge University Press.

This book offers a linguistic anthropological analysis of multilingualism among the Matsigenka, Quechua, and Spanish languages on the coffee frontier of Southern Peru, set against the backdrop of economic transformation and deforestation in the world’s last great forest.

For a first time the atlas maps the soil biodiversity of the entire planet, and provide s comprehensive analysis of human-induced threats to soil organisms and soil functioning, facilitating development of new policies to protect soil and soil organisms.

During the Leiden Science Family Day, you can take part in various workshops. You can also watch various demonstrations. Where will you go?

This study aims to provide a long time perspective of human landscape manipulation. Studying the roles of prehistoric foragers in past ecosystems is of great importance to establish the character of past 'natural' landscapes and to enhance the management of current ones.

We investigate water quality and want to understand the effects of human interference on aquatic biodiversity.

eLaw examines the role of law in the information society: how can law contribute to the proper functioning of information and communication technologies, and their use by citizens, businesses and governments?

Astronomers have discovered seven Earth-like planets around a dwarf star in our galaxy. Three of these planets are located in the habitable zone of this star, and may contain liquid water. ‘The next step is to study the atmospheres for signs of life. In Leiden we are experts in that area,‘ says planetary…

An international team led by Leiden astronomers has, after years of searching and defying the boundaries of a telescope, for the first time directly captured polarised light from an exoplanet. From this light they can deduct that a disk of dust and gas orbits the exoplanet. In this disk moons are possibly…

All the planets in our solar system orbit around the Sun in an ecliptical plane. This is to be expected because our solar system was formed from a so-called protoplanetary disc. PhD candidate Anna Miotello has studied these kinds of discs and how they influence the formation of stars and planets. PhD…

Astronomers at Leiden University have discovered the first planets using a new instrument: the planet hunter MASCARA. This instrument, developed at Leiden Observatory, looks specifically for planet transitions around the brightest stars in the sky, which surprisingly enough have so far have hardly been…

In a new video lecture (in English) on Universiteit van Nederland, astrophycisist Yamila Miguel tells us about the discovery of the most bizarre planets outside of our solar system.

An international team of astronomers have become the first in the world to detect isotopes in the atmosphere of an exoplanet. It concerns different forms of carbon in the gaseous giant planet TYC 8998-760-1 b. The research will be published in the scientific journal Nature on Thursday.

The James Webb Space Telescope has found evidence of carbon dioxide (CO₂) in the atmosphere of a giant planet 700 light years away. This result provides insight into the composition and formation of this gas giant and shows what James Webb is capable of. The research by the international group of astronomers,…

The new MASCARA-facilty in Chile has achieved first light. This new facility will seek out transiting exoplanets as they pass in front of their bright parent stars and create a catalogue of targets for future exoplanet characterisation observations.

What is Planet A? A new exhibition in the Old Observatory sheds light on how we all have different perceptions of earth. In five art installations, visitors are confronted with their own beliefs and how these differ from those of others.
