The largest operational telescope in the world is a 236.2-inch reflecting telescope in the Caucasus Mountains of Russia.
Assembled in October 1970, it is 80 feet long, weighs 935 tons, and contains a mirror which weighs 78 tons by itself.
The light-gathering power of this telescope is so great that it can detect the light of a single candle, 15,000 miles away.
The range of this gargantuan instrument encompasses the entire observable universe.
