The combining infrastructure, the Square Kilometre Array Observatory (SKAO), and headquarters, are located at the Jodrell Bank Observatory in the United Kingdom. The SKA cores are being built in the Southern Hemisphere, where the view of the Milky Way galaxy is the best and radio interference is at its least. The name refers to the notional size of the telescope's collecting area, not to the extent of the entire telescope array, which is far larger. Conceived in the 1990s, and further developed and designed by the late-2010s, the intention is that when completed it will have a total collecting area of approximately one square kilometre as originally conceived. The design of the first phase of SKA, scheduled as of 2025 for science operation in 2032, consists of 21,000 square metres (0.021 km2) of collecting area of dishes. It...
