Australia’s national science agency, CSIRO, helped launch construction of the Square Kilometre Array (SKA) Observatory’s SKA-Low telescope at Inyarrimanha Ilgari Bundara, the CSIRO Murchison Radio-astronomy Observatory on Wajarri Country in Western Australia (WA).
The global SKA Observatory (SKAO) announced the start of on-site construction activity for both their telescopes, SKA-Low in Australia and SKA-Mid in South Africa. The SKA-Low telescope will be the first mega-science project co-hosted in Australia and will explore the Universe in more detail than ever before, transforming the current understanding of the cosmos and benefitting society through global collaboration and innovation.
The SKA project aims to help Australian expertise remain at the forefront of discovery as an example collaboration to drive innovation, especially the collaboration of the Wajarri Yamaji, Traditional Owners and native title holders of the telescope site.
The progress of the SKA project over the past two decades has allowed researchers to see further into the universe than ever before. It has driven innovation and inspired generations both new and old through the development of technologies to solve great challenges facing our planet by better understanding the universe.
The start of SKA-Low construction on site is the culmination of many dreams, both within CSIRO and the global astronomy community, and the next step on this journey of discovery. CSIRO is the SKAO’s operations partner for the SKA-Low telescope in Australia and holds multiple contracts for SKA-Low construction activities.
The SKA-Low telescope will spread across 74 km end-to-end at the WA observatory site alongside existing instruments including CSIRO’s ASKAP radio telescope.
The SKA-Low Telescope Director stated that the SKAO was pleased to have established operations and engineering centres in Australia, where SKAO works closely with CSIRO as operations partner. She noted that CSIRO has been involved in the SKA project since its inception and have been leaders in radio astronomy science and technology for more than 70 years. The SKA Observatory welcomes this partnership with CSIRO to build and operate the SKA-Low telescope in Western Australia, she added.
CSIRO is also a foundation member in other key SKA project partners in Australia, including the Pawsey Supercomputing Research Centre and the Australian SKA Regional Centre.
More about CSIRO’s role in the SKA project
Australia is a member of the international organisation established to build and operate the world’s most powerful radio astronomy facility, the SKA Observatory (SKAO). The SKA Observatory will consist of two radio-telescopes, one in Australia (SKA-Low), and one in South Africa (SKA-Mid). The two telescopes will observe the sky at different radio frequencies and complement each other scientifically.
CSIRO will be the operating partner for the SKA-Low telescope, as well as hosting the telescope itself at Inyarrimanha Ilgari Bundara, our Murchison Radio-astronomy Observatory in Western Australia.
SKA-Low will consist of an array of 131,072 Christmas tree-shaped antennas, grouped in 512 stations, each with 256 antennas. Several of these antenna stations will be placed in the centre and the rest will span out along three spiral arms, stretching 74 kilometres end to end. SKA-Low will operate at frequencies between 50 and 350 MHz, like FM radio and TV broadcasts.
In addition to its role as operations partner and managers of the telescope site, CSIRO will also contribute to the construction of the SKA-Low Telescope. CSIRO:
- Led the infrastructure design work and is collaborating with industry partners to manage the site infrastructure construction process. This includes its work with industry partner Aurecon to manage the infrastructure contracts in Australia, including the contract with an Australian-based business.
- Is working with university and industry partners to oversee the installation of SKA-Low antenna stations.
- Is managing the assembly, integration, and verification process – the work to connect and check all the individual sub systems and products are working correctly – together with international institutions.
- Is working with international research institutions to develop the central signal processing system of the telescope, the backend of the telescope that takes the signals from each antenna station and combines them before sending that information to the science data processing system.
- Is working with university partners to design the science data processing system, the supercomputer software that takes the data from the telescope and outputs the images astronomers use to study the universe.
