Pioneers of Radio Astronomy

The Square Kilometre Array will be the largest radio telescope ever built and will produce science that changes our understanding of the universe. In Africa the SKA will be built in South Africa and eight other African Countries. The South African Radio Astronomy Observatory (SARAO), a facility of the National Research Foundation, is responsible for managing all radio astronomy initiatives and facilities in South Africa, including the MeerKAT Radio Telescope in the Karoo, the Geodesy and VLBI activities.
