description SKA Observatory Overview
The Square Kilometre Array Observatory (SKAO) is an intergovernmental organization headquartered in the United Kingdom tasked with building and operating radio telescope networks. The project features sites in South Africa, utilizing dish antennas for mid-frequency observations, and in Australia, utilizing aperture array antennas for low-frequency observations. When fully operational, the combined collecting area of the telescope arrays will span approximately one square kilometer. The observatory is designed to facilitate research into dark matter, galaxy formation, and astrobiology.
help SKA Observatory FAQ
Why is the SKA Observatory being built on two continents?
The project divides its observing work between SKA-Mid in South Africa and SKA-Low in Western Australia. The two telescope arrays cover different radio-frequency ranges, allowing astronomers to investigate a wider variety of cosmic phenomena.
What will the SKA Observatory actually study?
SKAO scientists plan to study subjects including the early universe, galaxy evolution, cosmic magnetism, pulsars, and possible signatures of extraterrestrial technology. Its pulsar observations may also provide unusually demanding tests of Einstein's theory of general relativity.
Is the Square Kilometre Array a single enormous dish?
No. SKA-Mid uses dish antennas in South Africa, while SKA-Low uses large fields of smaller antennas in Australia and combines their signals through interferometry.
Where is the SKA Observatory headquartered?
SKAO's global headquarters is at Jodrell Bank in the United Kingdom. Construction at the telescope sites is coordinated with SARAO in South Africa and CSIRO in Australia.
