Ooty Radio Telescope 1970 and continues to be one of the most sensitive radio telescopes in the world. Observations made using this telescope have led to important discoveries and to explain various phenomena occurring in our solar system and in other celestial bodies. The reflecting surface of the telescope is made of 1100 thin stainless-steel wires running parallel to each other for the entire length of the cylinder and supported on 24 steerable parabolic frames. An array of 1056 half-wave dipoles in front of a 90 degrees corner reflector forms the primary feed of the telescope. It has an angular resolution of 2.3deg
