India’s are in Allahabad, Bangalore, Bhubaneswar, Calicut, Chennai, Coimbatore, Gorakhpur, Guwahati, Hyderabad, Jaipur, Kolkata, Lucknow, Mumbai, Nagpur, New Delhi (two), Patna, Thiruvananthapuram, Tiruchirappalli.
China’s are in Beijing, Hong Kong, Macau, so in the whole of China “proper” there is only one, at least according to Wikipedia. (This blog has few readers in China, many in India.)
Bangladesh has one, in Dhaka. Pakistan two, in Karachi and Lahore. Sri Lanka, where Arthur C Clarke lived, one, in Colombo. Japan thirty-one. Korea apparently none. Africa three, but only one between Alexandria and Johannesburg: in Accra. Italy, Spain, Poland, Mexico many. The UK many, but in 2006 the London Planetarium (opened 1958, its high dome unlike any other I can think of) was closed and the space linked to Madame Tussauds. Shows about celebrities and others replaced astronomical projections.
This was five years after the removal of elephants from London Zoo. Scenes of ’60s childhood memories. Battersea Funfair closed in 1974.
A new planetarium opened in Greenwich in 2007.
Modern planetariums used to depend on technology developed by Zeiss in Jena, but many are now digital. The first public Zeiss cosmic projection was at the Deutsches Museum in Munich on October 21 1923.
Planetarium in Berlin, 1939, Deutsches Bundesarchiv (did the lower part of the design give the idea for extraterrestrial insect invaders in the ’50s, the upper the idea for Daleks in the ’60s?)
