The Nehru Planetarium is especially popular with Mumbai's public and visitors, particularly the audio-visual shows at the sky theatre. On special occasions, like during the recent appearance of Halley's Comet, a telescope was kept out for public sky-watching. Adjoining is the Nehru Science Centre and a children's science park. At the Planetarium, an image of the sky as seen from anywhere in the world at any time, past, present and future 270,000 years either way, can be viewed. Shows in English are held twice a day daily at 3 and 6 p.m. except on Mondays when the planetarium and also the Nehru Science Museum are closed
