While the total surface area of all radio telescopes determines the observation sensitivity of the SKAO, the maximum distance between two telescopes in such an array is decisive for the resolution of the observed objects, which is equally important. Australia will initially host more than 130,000 dipole antennas receiving low-frequency radio waves, with the ambitious goal of expanding this number to one million. When completed, nearly 200 antennas with a total surface area of 33,000 m 2 and a maximum distance of 150km between each one will be in operation. The desert regions of South Africa provide an ideal, quiet backdrop for the mid-frequency array, which will form a crucial part of the SKA intercontinental telescope. Headquarters in Manchester, radio telescopes in Australia and South AfricaĬonstruction of the first configuration of the SKA network in South Africa and Australia will be managed and coordinated from the SKAO headquarters at the Jodrell Bank Institute near Manchester (UK).
In the long term, the SKAO will become a major global astrophysics project, complementing the activities of the European Space Agency (ESA) and the ESO. It will also allow scientists to gain insights into the formation and development of the first stars and galaxies following the Big Bang, the role of cosmic magnetism, the nature of gravity and possibly even life elsewhere in the universe. The SKAO will be the most sensitive array of radio astronomy telescopes ever developed and built, with the necessary resolution for detecting signs of planets similar to the Earth several hundred thousands of light years away. This makes the SKAO the second intergovernmental organisation dedicated to astronomical research after the European Southern Observatory (ESO). The Convention came into force in December 2020 following its ratification by five signatory states, including the three host countries. Further countries, including India, Sweden and Switzerland, are expected to join in due course. The scale of the telescope represents a giant leap forward, both in terms of technology and computing, allowing scientists to observe and measure the universe in unprecedented detail.Īfter two and a half years of multilateral negotiations led by Italy, the SKAO Convention was signed in Rome in March 2019 by Australia, China, Italy, the Netherlands, Portugal, South Africa and the United Kingdom. This huge scientific project will be directed and overseen from the SKAO’s headquarters in Manchester (UK). The telescope, which is to be located in Australia and South Africa, will have a collecting area of over one square kilometre. In June 2021 the SKAO Council approved the construction of the largest radio telescope in the world. The Square Kilometre Array Observatory (SKAO) became an intergovernmental organisation in February 2021. Square Kilometre Array Observatory SKAO (astronomy) Languages
