Located in Worli the Nehru Science Museum with sound light gallery has an attractive childrens section. It is the only place, which recreates the image of sky as seen from anywhere on earth at any time. It also has a collection of warplanes, which served the Indian air force. Nehru planetarium was commissioned in 1977 and designed by one of India's finest architects I.M.Kadri. Nehru Centre, a trust headed by the Chief Minister of Maharashtra State, runs it. An astronomical exhibition, comprising of 40 exhibits (transparencies and working model) explain the cosmos. In the auditorium, a breathtaking 'Sky Show' captures the very essence of the Milky Way or Akashganga. Two hundred projectors are simultaneously trained onto a hemispherical ceiling made of aluminum. The effect is realistic and it is not surprising that the planetarium has attracted more than 3 million visitors.
