The Dawn of a New Era in Astronomy: The SKA Observatory’s First Image
The international SKA Observatory (SKAO) has marked a significant milestone with the release of the first image from its SKA-Low telescope in Australia. This early glimpse into the cosmos, captured using just a fraction of the telescope’s full capacity, promises a future of unparalleled scientific revelations.
A Glimpse into the Cosmos
The SKA-Low telescope, currently under construction in remote Western Australia, is one of two telescopes being built by the SKA Observatory. The first image, produced using data from just 1,024 of the planned 131,072 antennas, showcases an area of the sky equivalent to approximately 100 full Moons. This image reveals around 85 of the brightest known galaxies in that region, each harboring supermassive black holes.
Did you know? The full SKA-Low telescope, once complete, will be sensitive enough to detect more than 600,000 galaxies in the same frame, providing an unprecedented view of the Universe.
The Power of Collaboration
The achievement of capturing this image is a testament to the collaborative efforts of scientists, engineers, and computer experts from around the world. Dr. Sarah Pearce, SKA-Low Telescope Director, highlighted the global effort behind this milestone:
“This is the culmination of effort from many talented and committed people across teams, organisations and continents,” she said. “Getting to this point has taken engineers, astronomers and computer scientists from all over the world, working for decades.”
Pro Tip: The SKA telescopes, including SKA-Low and its counterpart SKA-Mid in South Africa, operate by combining data from individual antennas spread over large distances, effectively working as one giant telescope.
The Road to Full Capacity
The SKA telescopes are being constructed in stages, with components contributed by member countries around the world. In Australia, SKA-Low is being built in collaboration with Australia’s national science agency, CSIRO. The observatory site has been established with the support of the Australian and Western Australian governments.

The Promise of Future Discoveries
The first image from SKA-Low is just the beginning. SKAO Director-General Professor Philip Diamond emphasized the significance of this milestone:
“With this image, we see the promise of the SKA Observatory as it opens its eyes to the Universe,” he said. “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.”
