NEW DELHI, INDIA: Indian spectators watch the image of the rare celestial event at the Nehru Centre Planetarium in New Delhi, 08 June 2004, when planet Venus moved between the earth and the sun and appeared as a small black dot. A Venus transit occurs when the sun and the orbit planes of the second and the third planet are in a direct line, viewed from the earth this makes it seem like a mini-eclipse, an event seen for the time since 1882.
