Kim Chakanetsa discusses the wonders of the sky with two world-renowned astronomers.

Dr Ewine van Dishoeck is a Dutch astronomer and chemist who has been involved with the development of the James Webb Telescope, the largest optical telescope in space. A professor of molecular astrophysics at the University of Leiden, her work in researching the potential existence of water in space could help find answers to the biggest questions, including whether life is possible on other planets.

Dr Catherine Cesarsky is an Argentinian and French astronomer. Her research in astrophysics has included the composition of galactic cosmic rays and how stars are formed. As president of the Square Kilometre Array telescope project she’s directing an international effort to build the world’s largest radio telescope.
