This animation shows the various stages of delivery of the SKA-Low telescope over the coming years, and the images it is expected to be able to produce of the same area of the sky as its first image, released on 17 March 2025.
The 1,024 antennas used to produce that first image represent less than 1% of the full telescope and are spread over a distance of less than 6 km. They revealed 85 galaxies in an area of the sky equivalent to 100 full moons over a 7-hour observation. By 2026/2027, another 16,000 antennas will make SKA-Low the most sensitive radio telescope of its kind in the world and enable it to detect over 4,500 galaxies in the same area of the sky. By 2028/2029, SKA-Low will count over 78,000 antennas and be able to detect more than 23,000 galaxies in this field. The full SKA-Low telescope will count more than 130,000 antennas and spread over 74 km. Deep surveys performed of this area of the sky from 2030 will be able to reveal up to 600,000 galaxies.
