Australia on Monday started building a vast network of antennas in the Outback, its section of what planners say will eventually become one of the most powerful radio telescopes in the world.
When complete, the antennas in Australia and a network of dishes in South Africa will form the Square Kilometer Array (SKA), a massive instrument that will aim to untangle mysteries about the creation of stars, galaxies and extraterrestrial life.
The idea for the telescope was first conceived in the early 1990s, but the project was plagued by delays, funding issues and diplomatic jockeying.
The SKA Observatory’s Director-General Philip Diamond described the beginning of its construction as “momentous”.
The telescope “will be one of humanity’s biggest-ever scientific endeavors”, he said.
Its name is based on the planners’ original aim, a telescope that could observe a one-square-kilometer surface, but the current South African and Australian sections will have a combined collecting area of just under half that, according to the observatory.
