  • MeerKAT measures the "fuel reserves" of galaxies in the past

    A global team of astronomers, including many based in South Africa, have measured the fuel for star formation in galaxies as they were 4 billion years ago. The researchers made use of the MeerKAT radio telescope to observe neutral hydrogen gas, which is the most abundant element in the universe, and the material from which stars are formed. Observation of distant galaxies was one of the prime design drivers for MeerKAT, which is built and run by the South African Radio Astronomy Observatory (SARAO).

  • Megamaser “Nkalakatha” discovered by astronomers using MeerKAT

    Using the MeerKAT radio telescope, a team of researchers from the University of the Western Cape, the University of Cape Town, Rhodes University, the South African Radio Astronomy Observatory and the South African Astronomical Observatory together with colleagues from 12 other countries have discovered a powerful megamaser – a radio-wavelength laser indicative of colliding galaxies. This is the most distant such megamaser found so far.

The SKA will be the largest radio telescope ever built and will produce science that changes our understanding of the universe. The SKA will be collocated in Australia and in Africa. In Africa the SKA will be built in South Africa and eight other African Countries. SKA South Africa (SKA SA) is responsible for the construction of the SKA in South Africa.

The South African MeerKAT radio telescope, situated 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. The MeerKAT telescope is an array of 64 interlinked receptors (a receptor is the complete antenna structure, with the main reflector, sub-reflector and all receivers, digitisers and other electronics installed).
