When was birla planitorium in Kolkata built - in fact that was the place where I went more out of curiosity to know about the unknown world of planets & stars and wished that all the cities in India must have such planitoriums to inculcate the interests of outer world among the people & encourage the children to go to these places to enrich their knowledge.
