KAT-7 is the world’s first radio telescope built in the Karoo, South Africa’s semi-desert hinterland. It’s the basis for what’s known as the MeerKAT array, a world-class radio telescope that will be made up of 64 dishes designed to do ground-breaking science.
All of this is just a prec-cursor to what people are calling the Square Kilometre Array (SKA). A plan to array thousands of receptors extending out to distances of 3,000 km from a central core region. The SKA will be the largest and most sensitive radio telescope ever built, used to address fundamental unanswered questions about our Universe including how the first stars and galaxies formed after the Big Bang, how galaxies have evolved since then, the role of magnetism in the cosmos, the nature of gravity, and the search for life beyond Earth.
Sites in South Africa and Australia have been short-listed to host the central core of the SKA telescope. If located in South Africa, the SKA antennas would extend from the Karoo as far out as the Indian Ocean islands. A decision is expected to be made later this month.

Did you know? The Karoo is ideal for stargazing – it’s one of the darkest spots on earth with very little light pollution. Sutherland, in the Karoo, is home to the renowned SALT Observatory where you can do night time star gazing of the celestial big five.
