The Square Kilometre Array (SKA)

An International Radio Telescope for the 21st Century

Reference design concept for the SKA

Radio astronomy has a remarkable track record of discovery - including the discovery of pulsars, quasars, the cosmic microwave background, complex molecules in interstellar space, the existence of gravitational waves and the first extra-solar planets. Yet, all this was accomplished with technology largely from the 1960s and 1970s. Astronomers from all over the world are now working toward constructing a next generation radio telescopes, using 21st century hardware and software, the Square Kilometre Array (SKA). The SKA will have extreme sensitivity, be able to image vast fields of view, and to cover huge fractions of the radio spectrum simultaneously. Through these new capabilities, entirely new types of science become possible. SIfA is heavily involved in developing the SKA science case, and in building and using SKA prototypes.
