The main goal of the THEOR CHEM group, headed by Prof. Geert-Jan Kroes, is to characterize, and to accurately predict the outcome of chemical reactions at gas-solid and liquid-solid interfaces. Here the solid surface is typically a metal or an ice surface. These goals are important to many areas in…

Science education project Space Awareness engaged 230,000 people in 68 countries with the excitement and challenges of space sciences and technologies. After three years, the project coordinated by Leiden Observatory came to an end in March and has now been evaluated.

Meticulous analysis of hundreds of photographic plates from the star J1407 between 1890 and 2007 show no stellar eclipses. Robin Mentel, a master student at Leiden University, could not detect eclipses of the star J1407 by a planet hypothesized to have giant rings, called J1407b. However, an eclipse…
