Square Kilometre Array Observatory (Australia)

The Proposed Project

The SKAO is a global radio astronomy observatory that will enable transformational science about the universe, the fundamental laws of physics and the prospects for life on other planets.

The SKAO is one observatory, operating two telescopes on two continents (Australia and South Africa), with headquarters in the United Kingdom. The initial phase of the SKA (Phase 1), will consist of 197 radio dishes located in South Africa and 131,000 antennas located in Australia.

In Australia, the SKAO site is located in the Murchison shire, inland from Geraldton, Western Australia.  The Australian Murchison Widefield Array is located there.  It is a precursor instrument to the Square Kilometre Array telescope in Australia and will be integrated into Phase 1.

The SKAO is designed to deliver transformational science for at least 50 years. The aim is to build and operate a sustainable observatory, and work to minimize any likely adverse environmental effects from the construction and operation of the telescopes over its lifetime.
