What Square Kilometre Array does

Square Kilometre Array Observatory (SKAO) is an intergovernmental organization established in 2021 to build and operate the world's two largest radio telescope networks: SKA-Low in Western Australia and SKA-Mid in South Africa's Karoo region. Headquartered at Jodrell Bank in the United Kingdom, SKAO is governed by 14 member states, with France acceding as the most recent member in June 2026. The organization originated from a 1990s concept that matured through decades of design and prototyping before formal treaty-level establishment.

SKAO's core technical product is a distributed sensor network — tens of thousands of antennas and dishes spanning two continents — connected by high-bandwidth data links to a centralized correlator and the global SKA Regional Centres network. Once fully operational in 2029, the observatory is projected to generate approximately 700 PB of calibrated science data per year, processed through a purpose-built data pipeline. Major construction milestones include SKA-Low's first light in April 2025, SKA-Mid's first fringes in January 2026, and the June 2026 release of the SPICE_RACS cosmic magnetic field map produced in collaboration with CSIRO.

SKAO does not operate a commercial revenue model. It is funded through assessed contributions from member states, with science data and derived products distributed on an open-access basis to the global scientific community. The go-to-market model is therefore community-led: research outputs are consumed by universities, national observatories, and research institutes rather than priced per seat or per dataset. This structure makes SKAO functionally a public scientific infrastructure provider, with mission success measured by scientific citations, data deliverables, and member-state renewal rather than commercial revenue or profit.

Core offering

SKAO operates the two largest radio telescope arrays in the world—SKA-Low in Australia and SKA-Mid in South Africa—producing radio astronomy observations and scientific data products for the global scientific community. Its offerings include the telescope facilities themselves, simulated and science data products, software tools for data processing and analysis, and a distributed network of SKA Regional Centres that deliver computing resources and data access to researchers worldwide.

Product overview

The SKA Observatory (SKAO) is building the two largest telescope arrays in the world—the SKA-Low array in Australia and the SKA-Mid array in South Africa—made possible through a global collaboration. SKAO operates as an intergovernmental organisation offering radio astronomy infrastructure to scientists worldwide. The portfolio includes two core telescope products (SKA-Low and SKA-Mid), software tools for data processing and analysis, simulated data products for preparation and testing, SKA Regional Centres providing distributed computing infrastructure, and science data products derived from observations. The SKA telescopes will generate approximately 700 petabytes of data annually when fully operational in 2029.

Partnerships

Three partnerships are on record, tiered core.

• France (14th Member State)coreStrategic or Co-development Partner · 1 June 2026France became the 14th member state of SKA Observatory in June 2026, joining the intergovernmental organization that operates the world's largest radio telescope arrays. This membership represents continued expansion of the international scientific collaboration.
• CSIRO (Australia's National Science Agency)coreStrategic or Co-development PartnerCSIRO leads the global team that produced the SPICE_RACS cosmic magnetic field map using the ASKAP radio telescope at the Murchison Radio-astronomy Observatory. CSIRO operates the observatory site where SKA-Low is being constructed.
• International Scientific ConsortiumcoreStrategic or Co-development PartnerGlobal team led by Australia's CSIRO produced the largest-ever cosmic map of magnetic fields by measuring light from nearly 4 million galaxies. The dataset has been published and made freely available to scientists worldwide.

Regional players

• Five-hundred-meter Aperture Spherical Telescope (FAST): Chinese single-dish radio telescope, currently the world's largest filled-aperture radio telescope. Comparable as a flagship national radio astronomy facility, though single-dish rather than interferometric and focused on Chinese-led science rather than the SKA's multi-nation model.

Broad incumbents

• European Space Agency (ESA): Intergovernmental space research organization with similar membership and funding structure. Comparable institutional model (treaty-based, member contributions), though focused on space-based astronomy/observation rather than ground-based radio telescopes.
• National Radio Astronomy Observatory (NRAO): US-based operator of the Very Large Array (VLA) and Very Long Baseline Array, funded by the National Science Foundation. Comparable as a publicly funded radio astronomy facility offering telescope time and data products to the research community; SKAO is its international mega-scale counterpart.
• European Southern Observatory (ESO): Intergovernmental astronomy organization operating large ground-based telescopes (VLT, ALMA, ELT). Closely comparable to SKAO in intergovernmental structure, member-state funding model, and mission to provide global astronomical research infrastructure, though ESO focuses on optical/IR/mm wavelengths rather than radio.

Others

• CERN: Largest intergovernmental scientific research organization (particle physics). Comparable as a benchmark intergovernmental mega-science facility funded by member states with global data access; cited frequently as the model for how SKAO structures international collaboration.

Direct peers

• Atacama Large Millimeter/submillimeter Array (ALMA): Large-scale radio/millimeter interferometric array in Chile operated by an international partnership. Directly comparable to SKA-Mid as a global, multi-element interferometric radio telescope delivering high-resolution astronomy data to an international scientific community.
• LOFAR (LOw-Frequency ARray): European low-frequency radio telescope network led by ASTRON in the Netherlands. Direct functional overlap with SKA-Low as a low-frequency aperture-array telescope; LOFAR is widely considered SKA-Low's precursor.
• Murchison Widefield Array (MWA): Low-frequency radio telescope at the same Murchison Radio-astronomy Observatory in Western Australia where SKA-Low is being built. Direct precursor/peer in technology and site, operated by an Australian-led consortium.
