Background of SKAO Project Simplified – SKAO Project Details
History of SKAO Project: The Square Kilometre Array (SKA) project, conceived in 1991, emerged from international collaboration, officially forming as the SKA Organisation in 2011. In the early stages, China presented an ambitious proposal to host the SKA, envisioning the Kilometer-square Area Radio Synthesis Telescope (KARST).
However, the project ultimately found its home in Australia and South Africa, with the Murchison Radio-astronomy Observatory designated as the primary Australian site.
The project unfolds in two phases: SKA1, the current phase, and a potential expansion known as SKA2.
PrepSKA, initiated in 2008, led to the full SKA design in 2012, and Phase 1 construction was initially slated for 2018-2020, with Phase 2 completion projected in 2025. Jodrell Bank Observatory in the UK was announced as the project headquarters in April 2011.
Concerns were raised about the Australian candidate site, prompting a scientific working group to explore implementation options.
Ultimately, in May 2012, it was decided to split the SKA between South African and African sites and Australian and New Zealand sites. New Zealand, while initially part of the SKA Organisation, withdrew from the project in July 2019.
Construction contracts commenced in 2018, with the expectation that scientific observations using the fully completed array would begin no earlier than 2027.
The SKAO was officially founded in Rome on March 12, 2019, by seven initial member countries, including Australia, China, Italy, the Netherlands, Portugal, South Africa, and the United Kingdom. India and Sweden were expected to join, with eight other countries expressing future interest.
As of November 2020, four precursor facilities were operational, including MeerKAT, HERA, ASKAP, and MWA. The construction phase officially began on December 5, 2022, across Australia and South Africa. Notably, the Indian government’s approval in January 2024 to join the SKA project, accompanied by a financial commitment of ₹1,250 crore, marked a crucial step toward formal ratification.
The SKA represents a groundbreaking endeavor in radio astronomy, aiming to unravel the mysteries of the universe through international collaboration and cutting-edge technology. Its establishment marks a testament to humanity’s collective pursuit of knowledge and understanding the cosmos on an unprecedented scale.
What is a Radio Telescope?
A radio telescope is a specialized instrument designed to detect and study radio-frequency signals emitted by celestial objects. Unlike optical telescopes, which observe visible light, radio telescopes capture radio waves emanating from stars, galaxies, and other astronomical sources.
These telescopes consist of large, parabolic antennas that collect and focus radio signals onto receivers. By analyzing these signals, scientists can unveil hidden aspects of the universe, such as the composition, structure, and behavior of cosmic entities.
Radio telescopes are crucial for exploring celestial phenomena, including pulsars, quasars, and galaxies, providing insights into the vast and diverse realms of the cosmos.
