To look for atmospheres around planets outside our solar system is to look for extraterrestrial life. Astronomist Sebastian Zieba used data from the James Webb Space Telescope to study small rocky exoplanets but found no aliens yet. However, his findings are still very interesting for future observations.…

Researchers using NASA’s James Webb Space Telescope may have detected atmospheric gases surrounding 55 Cancri e, a hot rocky exoplanet 41 light-years from Earth. This is the best evidence to date for the existence of any rocky planet atmosphere outside our solar system.

A group of astronomers led by Leiden PhD student Sebastian Zieba has discovered using the James Webb Space Telescope (JWST) that the rocky exoplanet TRAPPIST-1 c has a thin atmosphere. Although the planet is nearly identical to Venus in size and temperature, and was expected to have a thick atmosphere,…

An international team of researchers led by astronomers from Leiden University (the Netherlands) has produced the first sharp radio maps of the universe at low frequencies. Thanks to a new calibration technique, they bypassed the disturbances of the Earth's ionosphere. They used the new method to study…

A team of European astronomers has found a silicate-based weather system on a cloudy gas planet around the star WASP-107. It is the first time astronomers have found silicate clouds and rain. They also conclude that temperatures deeper in the atmosphere are rising rapidly. 'The presence of clouds has…

The night side of exoplanet WASP-43b, to the surprise of astronomers, does not appear to contain methane. It is likely that extreme winds do not allow enough time for methane to form in detectable amounts. This is the conclusion of an international team of scientists, with Leiden and Amsterdam contributions,…

Six programmes in the Faculty of Humanities have been awarded the designation 'top programme' by the Keuzegids. These are the bachelor’s in German Language and Culture, Greek and Latin Language and Culture, Latin American Studies, Ancient Near East Studies, Religious Studies and Russian Studies.

These potential social scientists could get a taste of the study programmes and the atmosphere of our Faculty during the presentation sessions, at the information market and…

To what extent does exoplanet Proxima b resemble our Earth? And is there some form of life present? Astronomers hope to find answers to these questions with the new European Extremely Large Telescope (ELT). An NWO research grant of €18 million will allow a Dutch consortium to continue building instruments…

Nerve pain is one of the most common side effects of chemotherapy. It is therefore one of the biggest reasons for cancer patients to stop treatment early.
