27/01/2026 – The SKA Observatory’s growing telescope array in South Africa, SKA-Mid, has achieved “first fringes” using two of its dishes, a milestone that demonstrates it is operating as an interferometer for the first time.
“This is the first true test that all our systems are working together, and that the SKA-Mid telescope is alive as a scientific instrument,” said SKAO Director-General Prof. Philip Diamond.
“Having each dish observe the sky individually is an achievement, but having them operate in concert as one telescope is a much bigger technical challenge, and our teams have now achieved that milestone.”
SKA-Mid, like its counterpart SKA-Low in Australia, is an array where many individual antennas are connected by optical fibre to act like one much larger telescope, equivalent in size to the distance between its furthest antennas. "Fringes” are obtained when signals received by two or more antennas are combined successfully.

Two of SKA-Mid's 15m-diameter dishes were used together to achieve the result, observing a radio galaxy estimated to be around 2.6 billion light years away.
“This source has been well studied so we know what the signal should look like, and that’s what we observed with this first fringes result. It confirms that all our hardware and software systems are working as we designed them to do, giving us confidence as we begin to commission the telescope,” said Dr Betsey Adams, SKA-Mid Commissioning Scientist.
“That includes seeing that the dishes can track across the sky in a coordinated way under the control of the telescope manager software, the receivers are being cooled to the required temperature of minus 250°C, the synchronisation and timing system is accurately timing signals from the different dishes to a billionth of a second, and the correlator is correctly processing and aligning the data.”
SKA-Mid now has seven dish structures assembled on site in the Northern Cape, with a further 12 on their way from the manufacturers CETC54 in China. When complete the telescope will comprise 197 dishes, including the integration of the existing MeerKAT radio telescope built and operated by the South African Radio Astronomy Observatory (SARAO). The hardware and software for the SKA telescopes are being developed in the Observatory's member states, including Spain. Specifically, the time signal distribution and synchronisation system, which is key to performing interferometry. This technology has been developed by the Spanish company Safran Electronics & Defence Spain, based in Granada, which is also responsible for the same system for the SKA-Low telescope in Australia.
“Starting the year with this news is a huge boost for the teams that have worked extremely hard to see it happen, including SKAO and SARAO colleagues, and our global and local partners who are contributing to the infrastructure, hardware and software for SKA-Mid,” said Ben Lewis, SKA-Mid Senior Project Manager.
“With all we’ve learned from these months building up to first fringes, we’re in a strong position to achieve our next milestone – the first image from a four-dish array within the next few months – and then to see SKA-Mid gradually grow in size and capabilities from there.”
Across the ocean in Australia, the SKA-Low telescope continues to grow at pace. Around 70 antenna stations, each comprising 256 antennas, have now been installed at Inyarrimanha Ilgari Bundara, the CSIRO Murchison Radio-astronomy Observatory on Wajarri Yamaji Country in Western Australia. Last year its first image was released, using an early version of the telescope comprising four connected stations – 1,024 antennas – or less than 1% of the complete telescope.
As work continues to commission stations and integrate them into the array, planning is underway for the start of science verification activities with SKA-Low in 2027, when the first data will be released to the community for test observations.
16/01/2026 – El equipo de coordinación de la participación nacional en el proyecto SKA asistió el pasado mes de diciembre a la II Jornada de Grandes Infraestructuras de Investigación del CSIC y al Big Science Industry Forum Spain (BSIFS).
The coordination team for the Spanish participation in the SKA project (SKA-Spain) took part in two national forums related to large scientific infrastructures, reinforcing the key role of the scientific community and national industry in areas such as scientific data management, Open Science, digital transformation, and artificial intelligence.
Within the framework of the II Jornada de Grandes Infraestructuras de Investigación del CSIC, held on 2nd December, Julián Garrido from the Instituto de Astrofísica de Andalucía (IAA-CSIC), and co-PI of the SKA-Spain coordination, participated in the round table “EOSC en el CSIC. Gestión de datos en las Grandes Infraestructuras de Investigación: estrategia, impacto y ciencia abierta”. During his intervention, Garrido presented the SKA Observatory (SKAO) as an example of an infrastructure that will foster Open Science, highlighting the challenges associated with managing massive data volumes (on the order of hundreds of petabytes per year). He also emphasized the role of the international SKA Regional Centres (SRCNet) as a key element to guarantee access, processing and scientific reuse of these data.
The discussion underscored the need for robust institutional strategies and sustained funding for data management, as well as the importance of integrating the FAIR principles and Open Science as foundational elements of scientific infrastructures. In this context, the efforts made in Spain to incorporate scientific reproducibility as a success metric within the SKA were highlighted, along with initiatives to ensure that, after embargo periods, data are integrated into public archives accessible to the scientific community. The potential role of the European Open Science Cloud (EOSC) as a reference framework to reduce technological barriers for researchers and data managers was also discussed.

The BSIFS also highlighted the importance of strengthening connections between large scientific infrastructures and the national industrial ecosystem, identifying the need for specialized talent, public–private cooperation, and regulatory frameworks that promote the responsible adoption of Artificial Intelligence. “The organization of this type of activity helps to establish highly valuable dialogues for the scientific community, the science industry, and society,” notes Verdes-Montenegro. In this context, the event organizers facilitated meetings between participants. The coordination team held formal meetings with seven companies that expressed interest in the SKAO and the SRCNet, as well as in potential future opportunities for industrial participation.

The coordination team for Spain’s participation in the SKA project is pleased to announce that the Spanish companies EOSOL and COMPOXI have successfully passed the Detailed Design Review (DDR) for the construction project of the sub-reflectors for the SKA-Mid radio telescope. This milestone represents a decisive step in Spain’s contribution to one of the most ambitious and large-scale scientific engineering projects of the 21st century.
The successful completion of this phase validates the developed technical design and paves the way for the manufacturing stage of the 44 sub-reflectors to be integrated into the SKA-Mid antenna array, currently under construction in South Africa. This achievement is the result of several months of close collaboration between EOSOL, COMPOXI, and the technical team at the SKA Observatory, and it highlights the advanced technological capabilities of the Spanish industrial sector.
The sub-reflectors—a critical component responsible for directing incoming signals to the receivers—have a diameter of 4.5 meters and are made of composite materials with a metallized surface to ensure both mechanical stability and demanding electromagnetic performance. Each unit comprises over 100 individual parts, including six main panels and three extensions, all of which must be assembled with high precision.
We emphasize the strong collaboration between COMPOXI, a company specialized in the design and manufacturing of composite structures, and EOSOL, a leading provider of engineering services for strategic sectors. This kind of synergy exemplifies the ability of the Spanish industrial sector to make substantial and effective contributions to large-scale international scientific infrastructures.
The SKA Observatory, with core sites in South Africa and Australia, will host the most advanced radio telescopes on Earth, enabling the global scientific community to explore the Universe with unprecedented resolution and scope. Spain’s active participation—at the institutional, scientific, and industrial levels—reinforces its role as a strategic partner within this intergovernmental organization.
It is worth noting that this contract has been partially funded by the European Union through the NextGenerationEU programme, managed by the Spanish Ministry of Science, Innovation and Universities. This reflects the significant impact of public investment in research and innovation on the international visibility and competitiveness of Spain’s technological capabilities.

29/05/2025 – The SKAO, a balcony to the Universe with its heart on Earth 05/29/2025 – SKAO, a balcony to the Universe with its heart on Earth, is the title of a public talk in the Lucas Lara lecture series, which will take place on Thursday, May 29 at 7:00 p.m. in the IAA-CSIC Auditorium, Granada, Spain.
The speaker is Lourdes Verdes-Montenegro, who has coordinated Spanish participation in this project since its inception. This is a great opportunity to learn how a large astronomical observational facility, with unprecedented sensitivity and complexity, is conceived, built, and organised. Also, to learn about the construction of these telescopes in remote regions of South Africa and Australia.
In this talk, we'll learn about the latest developments and Spain's participation in the project. We'll also learn about the status of the SKA International Network of Regional Centres, for which one node is being developed in Spain. These centres are essential for the community to access the vast amount of data the telescopes will generate and to benefit from tools, technical support, and specialised training.
From this point on, we will open a window to the lesser-known dimensions of SKAO: the challenge of interference caused by mega-satellite constellations, cooperation with Africa and Indigenous tribes in Australia, Open Science, respect for the environment, and the creation of opportunities beyond science. This is an invitation to observe the Universe with the most advanced technology... and with your feet firmly on the ground.
March 17, 2025 – The first image from the SKA-Low radio telescope was released today. SKA-Low is part of the SKA Observatory (SKAO) and is located in Australia. This marks a significant milestone in SKAO's mission to provide an unprecedented view of our universe.

The image covers an area of the sky approximately 25 square degrees in size, equivalent to about 100 full moons. It displays 85 of the brightest known galaxies in that region, all of which contain supermassive black holes. The image was obtained with an early version of the SKA-Low telescope, one of two telescopes being built by SKAO. This early version of SKA-Low consists of just 1,000 of the planned 131,000 antennas. Once completed, the telescope will be able to reveal many more objects; scientists estimate it will be able to detect more than 600,000 galaxies in the same region of the sky.
SKAO is currently building two radio telescopes: SKA-Low in Western Australia and SKA-Mid in the Northern Cape Province of South Africa. The telescopes are arrays of 15-meter parabolic antennas (SKA-Mid) and dipole antennas (SKA-Low), spread over large distances. Two Spanish companies, Safran Electronics & Defense Spain and EMITE, are playing a key role in the construction of SKA-Low, providing high-precision synchronization systems between the antennas and equipment for testing and validating electronic components. "Synchronizing the signals from the different antennas is crucial for combining them correctly. Furthermore, to avoid interference, it is necessary to test that all electronic components do not generate noise in radio waves that could affect the signal from the astronomical objects being observed," explains Dr. Julián Garrido, deputy technology coordinator at SKA-Spain, adding: "For this same reason, the telescopes are being built in remote, sparsely populated locations, minimising human-caused interference."
SKA-Low is being built at Inyarrimanha Ilgari Bundara, the CSIRO Murchison Radio Astronomy Observatory, which is located on the lands of the Wajarri Yamaji Aboriginal people, the traditional owners and native land title holders. The location's Aboriginal name, Inyarrimanha Ilgari Bundara, means "sharing the sky and stars", and reflects the commitment and collaboration between SKAO and the Indigenous peoples and cultures who inhabit the lands where its telescopes are being built.

The acquisition of this image has verified the telescope's operation and capabilities. Professor Philip Diamond, Director General of the SKAO, said the image marks the observatory's debut as a scientific facility. "With this image we see the promise of the SKA Observatory as it opens its eyes to the Universe," said Professor Diamond. "This first image is a critical step for the Observatory, and for the astronomy community; we are demonstrating that the system as a whole is working. As the telescopes grow, and more stations and dishes come online, we’ll see the images improve in leaps and bounds and start to realise the full power of the SKAO."
The SKAO telescopes are being built in phases, with components sourced from SKAO member countries around the world. Dr. Lourdes Verdes-Montenegro, coordinator of Spain's participation in the SKAO, highlighted the international nature of the observatory: "This milestone has been possible thanks to an international collaboration between scientists and engineers from academia and industry. Sixteen countries from five continents are participating in the SKA project, and the impact it is already having and will have will be global thanks to SKAO's commitment to the scientific community and international society as a whole."
The Spanish participation in the SKAO is funded by the Ministry of Science, Innovation and Universities, with the Andalusian Institute of Astrophysics (IAA-CSIC) responsible for the national scientific and technical coordination of the project.

27/02/2025 – The Spanish prototype of the SKA Regional Centre, under development by the IAA-CSIC, becomes the first centre to successfully complete its integration into SRCNet0.1, the first operational version of the international network that will constitute the scientific heart of the SKA Observatory (SKAO).
SKAO is an international organization building two state-of-the-art radio telescopes: SKA-Low in Australia, with over 130,000 dipole antennas for transmitting and receiving radio waves, and SKA-Mid in South Africa, with 197 parabolic antennas, each 15 meters in diameter. When the observatory's telescopes are operational, they will generate over 700 million gigabytes of data annually. All this data will be housed at SKA Regional Centres (SRCs), where it can also be accessed remotely. The various SRCs, distributed around the world, will be interconnected, forming a global network: SRCNet.
Last Monday, February 24, it was announced that the Spanish prototype of the SKA Regional Center, being developed at the Institute of Astrophysics of Andalusia (IAA-CSIC), was the first to complete the deployment and integration of the services required to become part of SRCNet0.1. This initial operational version of the international network will be fundamental for the functioning of the SKA Observatory (SKAO).
The Spanish prototype of SRC, called espSRC, is one of 17 national initiatives contributing to the development of SRCNet. “We have been working on this project since 2019, demonstrating our firm commitment to the development of SRCNet as a collaborative platform. Being the first center to deploy the necessary services to become an SRCNet0.1 node is a result of this commitment and close collaboration with the other international groups involved,” says Susana Sánchez-Expósito, technical coordinator of espSRC at the IAA-CSIC. “We currently have a fully functional system that has served more than 30 scientific projects in different branches of astrophysics,” she adds. Isabel Márquez, scientific director of the Severo Ochoa program at the IAA-CSIC, also highlights: “It is this multidisciplinary approach that makes the SRC prototype one of the key pillars, and a cross-cutting element in our scientific strategy, funded by our Severo Ochoa excellence project. Having an infrastructure of this level at our center positions Andalusia and Spain within the international SKA collaboration.”

For her part, Lourdes Verdes-Montenegro, a researcher at the IAA-CSIC, coordinator of Spanish participation in SKAO, and head of the espSRC, emphasizes that “SKAO embraces sustainability and open science among its founding principles, and our prototype stands out as a benchmark for implementing both aspects within the SRCNet.” Open science is based on the principle of research reproducibility. According to UNESCO, this approach is increasingly recognized as a fundamental accelerator for achieving the Sustainable Development Goals (SDGs). To this end, it is essential that data, methods, and analytical tools be available to society. “SKAO will change the way science is done: it will no longer be possible to work locally on our computers, and the SRCs will constitute the scientific core of SKAO, providing an environment that fosters and facilitates collaboration between international teams following the principles of open science,” concludes Lourdes Verdes-Montenegro.
