Murchison Radio-astronomy Observatory

It lies in a designated radio quiet zone located near Boolardy Station in the Murchison Shire of Western Australia, about 800 kilometres (500 mi) north of Perth on the traditional lands of the Wajarri people.

It is one of two core sites for the international Square Kilometre Array (SKA) project, the other being located in South Africa.

As part of this project, there have been two technology and science pathfinders, both established by 2012: Construction on the main large SKA-Low telescope started in December 2022.

[2][3][4] Then called, the Murchison Radio-Astronomy Observatory, it was founded by the CSIRO in 2009, near Boolardy, a former cattle station in Western Australia.

There are challenges involved in working out how to respect the cultural significance of the area, and how to build the infrastructure with minimal disruption to the landscape.

The neighbouring Wooleen Station has facilities for guests, and the owners are working with local governments to develop its tourism potential.

[2] The Australian Square Kilometre Array Pathfinder (ASKAP) was built by CSIRO and comprises 36 identical antennas, each 12 metres in diameter, working together as a single instrument.

The MWA is the first so-called large-N array, fully cross-correlating signals from 128 phased tiles of 16 crossed dipoles (each).

[15] The site has been named Inyarrimanha Ilgari Bundara, meaning "sharing sky and stars" in the Wajarri language.
