Square Kilometer Array Telescope

Sept. 20, 2024

Square Kilometer Array (SKA), the world’s largest radio telescope in the making, has carried out its first observations, signalling that at least a part of the yet-to-be-completed facility has become functional.

About Square Kilometer Array Telescope:

  • It is a state of the art, mega science international facility to build the world’s biggest and most sensitive radio telescope for addressing a wide variety of cutting-edge science goals.
  • Location: It is co-located in Australia(SKA-Low) and South Africa (SKA-Mid) with operational headquarters in the UK, is expected to revolutionize radio astronomy.
    • The array in South Africa is named SKA-Mid while the one in Australia is called SKA-Low, the names reflecting the frequency ranges they operate in.
    • It consists of a total of 1,31,072 lakh antennas, each measuring two-metres in height, will collectively form the SKA-Low.
    • The SKA-Mid will comprise 197 large parabolic dish antennas. Offering the largest bandwidth of observations, SKA-Low will operate from Australia in the frequency bandwidth 50 – 350 Mega Hertz while SKA-Mid is designated to operate in 350 MHz – 15.4 Gigahertz band in South Africa.
  • The facility is meant to observe the universe in a new way, and probe questions related to the origins of the universe, formation and evolution of galaxies and seeking the origins of life.
  • India became a member of SKA in December 2022.
  • Other countries involved in this project are - Canada, China, India, Italy, New Zealand, Sweden, and the Netherlands.
