Does life exist on other planets? Astrophysicist Ignas Snellen scrutinizes worlds that orbit other stars than our Sun. While distances are enormous, making exoplanets extremely faint, he devises techniques to study their atmospheric contens. He tries to find habitable planets, perhaps even a twin Earth. What do these remote worlds teach us about ourselves?

Prof. dr. Ignas Snellen is full professor in Astronomy at Leiden University and scientific director of Leiden Observatory. In 2022 he recieved the Spinoza Prize.
