  • The Government of India had given in-principal approval to the project in February 2016.
  • LIGO is the world's most powerful observatory that exploits the physical properties of light and space to detect and understand the origin of gravitational waves.
  • This observatory will help in better understanding of celestial objects like neutron stars and black holes and in-depth study of gravitational waves.
  • Each LIGO detector has two arms, each 4 kilometres long, consisting of 2-meter-wide steel vacuum tubes arranged in an "L" shape and anchored by a 10-foot-wide, 12-foot-tall concrete shelter. are covered, which protect the tubes from fire.
