This department is focused on research of stars. It focuses mainly on studies of hot stars (class Be), models of stellar atmospheres, dynamics of stellar winds and relativistic astrophysics. For this purpose uses the department the biggest telescope in Czech Republic - reflector with a 2m wide mirror. The head of the department is Jiří Kubát.
This department is located in Prague. It deals mainly with a research of effects of solar system on the Earth. The head of the department is Jan Palouš.
The Astronomical Institute is a direct descendant of an observatory founded at the beginning of 18th century by Jesuits in the Old town of Prague. After the first world war, the observatory has become a state observatory. In meantime, there was another observatory being built by Josef Jan Frič in Ondřejov which he donate to the Czech state in 1928. At the foundation of the Czechoslovak Academy of Sciences were these two observatories merged into one institution under the name Astronomical institute of Czechoslovak Academy of Sciences.
