The Square Kilometre Array (SKA) is an radio telescope project being planned to be built in Australia and South Africa. Conceived in the 1990s, and further developed and designed by the late-2010s, when completed it will have a total collecting area of approximately one square kilometre sometime in the 2020s. It will operate over a wide range of frequencies and its size will make it 50 times more sensitive than any other radio instrument. It will require very high performance central computing engines and long-haul links with a capacity greater than the global Internet traffic as of 2013. If built as planned, it should be able to survey the sky more than ten thousand times faster than before.
