The Square Kilometre Array (SKA) project is an international effort to build the world’s largest radio telescope, with eventually over a square kilometre (one million square metres) of collecting area.

• The SKA will eventually use thousands of dishes and up to a million low-frequency antennas that will enable astronomers to monitor the sky in unprecedented detail and survey the entire sky much faster than any system currently in existence.
• Thousands of SKA antenna dishes will be built in South Africa (in the Karoo), with outstations in other parts of South Africa, as well as in eight African partner countries.
