Known as the Square Kilometre Array, or SKA--as that was originally planned to be the total collecting area of its thousands of dish-shaped antennae--it was conceived of by an international group of astronomers in the early 1990s. No construction has yet begun. Indeed, no site has yet been chosen. However, in the vast quietness of the Karoo, a semi-desert in South Africa, a small prototype is already operating and its first images are, by all accounts, remarkable. The Karoo Array Telescope (KAT-7) consists of seven steerable dishes, each 12 metres across. As such, it is already the most powerful array-based telescope in Africa. It is, though, merely a test bed for MeerKAT, a device that will consist of 64 somewhat larger dishes and will be the most powerful instrument in the southern hemisphere as well as one of the three most sensitive in the world.
