Square Kilometre Array (SKA)

Square Kilometre Array (SKA) Project Logo

The Square Kilometre Array is the world's biggest radio telescope, to be built in South Africa and Western Australia over the coming decade. By measuring neutral hydrogen over cosmic time, accurately timing the signals from pulsars in the Milky Way, and detecting millions of galaxies out to high redshifts, it will address some of the biggest questions about the nature of gravity, dark energy, and how galaxies formed and subsequently evolved.
