Construction of a crucial datacenter supporting the Square Kilometre Array (SKA) project in Western Australia is almost finished, officials have announced.The facility incorporates specialized Faraday cages intended to prevent radio frequency interference that could compromise the telescope’s sensitive observations.
The SKA, an international collaboration, is building an unprecedented array of 131,072 antennae, collectively covering an area of approximately one square kilometer. This vast instrument promises to revolutionize our understanding of the universe,providing scientists with a powerful new tool for astronomical research.
Project Progress and Technical Specifications
Work on the enterprising SKA project commenced in 2022. Professor Philip Diamond, Director of the SKA observatory, reported that over 12,100 antennae have already been installed, alongside significant progress in laying power cables and optical fiber networks. The project is already seeing tangible results, paving the way for groundbreaking discoveries.
The newly constructed datacenter, located in the remote Murchison region of Western Australia, will house approximately 100 server racks. These servers utilize Field Programmable Gate Arrays (FPGAs) to efficiently process the enormous volumes of data-many terabytes daily-generated by the SKA.The processed data will then be transmitted to supercomputers in Perth via a high-bandwidth 10-terabit-per-second optic fiber link.
Did You Know? The Murchison region was selected for its remarkable radio quietness, minimizing interference from human-generated radio signals.
Shielding Against Interference: The Faraday Cages
Maintaining the integrity of the SKA’s observations requires an environment free from radio frequency (RF) interference. Even trace amounts of stray RF emissions from computer equipment could perhaps obscure the faint signals the telescope is designed to detect. To mitigate this issue, the datacenter is enclosed within two layers of Faraday cages – metallic structures designed to block electromagnetic energy.
Access to the shielded datacenter is meticulously controlled, resembling a science fiction airlock. Personnel must pass through a double-door system where the inner door remains locked until the outer door is securely closed, minimizing any potential RF leakage. Officials described a distinctive “Star Trek-like” sound accompanying the entry and exit procedures.
Future Outlook and Scientific Opportunities
While construction is anticipated to conclude around 2029, Professor Diamond revealed that the SKA team will invite research proposals for utilizing the telescope next year, with selected projects conducting pilot observations in 2027. The goal is to validate the facility’s performance and refine operational procedures.
“By then we will have the largest physical low-frequency telescope on the planet, and we will ask for ideas for objects to observe,” explained Professor Diamond. The team anticipates significant creative tension as scientists push the boundaries of the telescope’s capabilities.

Despite substantial progress, approximately 20 percent of the required funding remains outstanding. Professor Diamond expressed confidence in securing the necessary resources to complete the project.
Pro Tip: Radio astronomy relies on detecting incredibly faint signals from space. Shielding against terrestrial interference is crucial for maximizing the telescope’s sensitivity.
Understanding Radio Telescopes and Their Importance
Radio telescopes, unlike optical telescopes, detect radio waves emitted by celestial objects. This allows them to observe phenomena invisible to the human eye, such as the distribution of hydrogen gas in galaxies or emissions from distant quasars. The Square Kilometre Array represents the next generation of radio telescope technology, offering unprecedented sensitivity and resolution.
The SKA is expected to address fundamental questions in astrophysics, including the formation and evolution of galaxies, the nature of dark matter and dark energy, and the search for extraterrestrial intelligence. Its unique capabilities will enable scientists to probe the universe in ways never before possible.

The Unique Electromagnetic Challenges of Radio Astronomy
The Square Kilometre Array (SKA) project, with its significant presence in South Africa’s Karoo region, represents a monumental leap in radio astronomy. However, the extreme sensitivity required to detect faint signals from the early universe presents unique challenges, particularly concerning electromagnetic interference (EMI). Unlike optical telescopes shielded from light pollution, radio telescopes are vulnerable to both natural and man-made radio frequency interference. This is why the south African SKA data center employs, and crucially requires, a dual faraday cage system – a level of protection rarely seen in standard data center infrastructure. Understanding SKA data security isn’t just about digital threats; it’s fundamentally about protecting the signal integrity.
What is a Faraday Cage and Why is One Not Enough?
A Faraday cage, also known as a Faraday shield, is an enclosure formed by a conductive material (often a mesh or solid metal) that blocks electromagnetic fields. It works by distributing the charge around the exterior of the cage,effectively cancelling out the field within.
For the SKA, a single Faraday cage isn’t sufficient due to several factors:
* Low-Frequency Interference: Lower frequency EMI, often from terrestrial sources, requires a more robust and layered shielding approach.
* Increased Sensitivity: The SKA’s unprecedented sensitivity demands a considerably lower noise floor than traditional radio telescopes.
* Potential Cage Imperfections: Any gaps or imperfections in a single cage can compromise its shielding effectiveness,especially at lower frequencies.
* Ground Loops & Common Mode Noise: A single cage can inadvertently create ground loops,introducing noise into the system.
Thus,the SKA utilizes a dual Faraday cage design – a cage within a cage – to provide an exceptionally high level of EMI protection. This redundancy is critical for maintaining the integrity of the astronomical data. This is a key component of the overall SKA infrastructure.
The Dual Faraday Cage system at the SKA Data Center: A Deep Dive
The SKA’s dual Faraday cage system isn’t a simple replication of the same cage twice. Each layer is specifically engineered to address different aspects of EMI mitigation.
* Outer Cage: Constructed from a robust steel mesh, the outer cage primarily focuses on blocking medium to high-frequency EMI originating from external sources like cell towers, broadcast transmitters, and even atmospheric disturbances. it’s grounded to a dedicated,isolated grounding system to minimize noise.
* Inner cage: The inner cage, built with a denser, highly conductive material (often copper), targets lower-frequency interference and provides a more complete shield against any residual EMI that penetrates the outer layer. This cage is also meticulously designed to minimize internal reflections and resonances.
* Air Gap & Damping Materials: A carefully calculated air gap separates the two cages. This gap, combined with specialized damping materials placed between the layers, further reduces the transmission of electromagnetic energy.
* Filtered Power & Data Lines: all power and data lines entering the Faraday cages are rigorously filtered to prevent EMI from being conducted into the shielded environment. This includes fiber optic cables, which, while immune to EMI, can act as antennas if not properly grounded.
* Access Control & Shielded doors: Access to the inner cage is strictly controlled, and all entry points are equipped with shielded doors and gaskets to maintain the integrity of the shielding.
Benefits of a Dual Faraday Cage for the SKA
The investment in a dual Faraday cage system yields significant benefits for the SKA project:
* Enhanced Data Quality: Minimizing EMI directly translates to cleaner, more accurate astronomical data.
* Increased Sensitivity: A lower noise floor allows the SKA to detect fainter signals, pushing the boundaries of our understanding of the universe.
* reduced Data Processing Requirements: Less noise in the raw data reduces the computational burden of signal processing and analysis.
* Long-Term Data Integrity: Protecting the data from EMI ensures its long-term usability and value for future research.
* Protection of Sensitive Equipment: The cages
