The Southern African Large Telescope

The largest single optical telescope in the southern hemisphere

SALT is situated at the South African Astronomical Observatory (SAAO) field station near the small town of Sutherland, in the Northern Cape province, about 400 km from Cape Town. SALT is currently funded by a consortium of international partners from South Africa, the United States, Poland, India and the United Kingdom. The telescope has been in full science operation since 2011 and is realising its huge potential as Africa’s Giant Eye on the Universe.
