  • The Giant Metrewave Radio Telescope (GMRT), which is the world’s largest radio telescope facility operating at low radio frequencies, was shut down for a day on Wednesday since cyclone Nisarga’s predicted trajectory was close to its array of 30 fully steerable parabolic dishes of 45m-diameter antennas, spread out over a 30km region about 10km east of Narayangaon town on Maharashtra’s Pune-Nasik highway.
  • In May, it was instrumental in helping a team of international scientists discover a new class of powerful astronomical explosions caused by a Fast Blue Optical Transient, which simply put, is a super powerful explosion of a star.
  • The safe position with antennae pointing straight up ensures minimum cross section for the wind.
