The Southern African Large Telescope (SALT)


The Southern African Large Telescope (SALT) is the largest single optical telescope in the southern hemisphere and among the largest in the world. It has a hexagonal primary mirror array 11 metres across, comprising 91 individual 1m hexagonal mirrors. SALT is situated at the South African Astronomical Observatory (SAAO) field station near the small town [...]

South African Astronomical Observatory (SAAO)


Founded in 1820 and located in the leafy Southern suburbs of Cape Town, The South African Astronomical Observatory (SAAO) is the national centre for optical and infrared astronomy in South Africa. Its prime function is to conduct fundamental research in astronomy and astrophysics. It does so by providing a world-class facility to scientists. The SAAO [...]

C-Band All Sky Survey


New radio telescope in SA will also shed new light on the earliest moments of the universe: C-BASS South commissioning at Hartebeesthoek 27 March 2013 In the week that saw the release of the first results from the European Space Agency's Planck satellite, astronomers at the Hartebeesthoek Radio Astronomy Observatory (HartRAO) near Johannesburg are working [...]

African VLBI Network


The AVN is a network of VLBI-capable radio telescopes on the African continent, that will strengthen the science which the international VLBI community can do. The AVN will help to develop the skills, regulations and institutional capacity needed in SKA partner countries to optimise African participation in the SKA and enable participation in SKA pathfinder [...]

Hydrogen Epoch of Reionization Array (HERA)


The HERA (Hydrogen Epoch of Reionisation Array) radio telescope will be instrumental in detecting the distinctive signature that would allow astronomers to understand the formation and evolution of the very first luminous sources: the first stars and galaxies in the Universe. To solve the mystery of how we came to be where we are, astronomers [...]



The seven-dish MeerKAT precursor array, KAT-7, is the world’s first radio telescope array consisting of composite antenna structures. KAT-7 was primarily built as a precursor to the 64-dish MeerKAT radio telescope array and to demonstrate South Africa’s ability to host the SKA. However, it has proved to be a pioneering scientific instrument in its own [...]

The Square Kilometer Array (SKA)


The SKA project is an international effort to build the world’s largest radio telescope, with a square kilometre (one million square metres) of collecting area. The scale of the SKA represents a huge leap forward in both engineering and research & development towards building and delivering a radio telescope, and will deliver a correspondingly transformational [...]

The South African Radio Astronomy Observatory (SARAO)


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, and the Geodesy and VLBI activities at the HartRAO facility. SARAO also coordinates the African Very Long Baseline Interferometry Network [...]

MeerKAT radio telescope


The South African MeerKAT radio telescope, currently being built some 90 km outside the small Northern Cape town of Carnarvon, is a precursor to the Square Kilometre Array (SKA) telescope and will be integrated into the mid-frequency component of SKA Phase 1. MeerKAT’s make-up The MeerKAT telescope will be an array of 64 interlinked receptors [...]
