What is the biggest telescope? I remember seeing a documentary about the building of the biggest one ever. Can't remember what they called it. All I remember is they said it would be finished in five years, the mirror for it was enormous, it will apparently be able to see far away planets in extremely clear detail and it was transported to the destination at a speed of 5 Kilometres an hour on a big truck and men were walking beside it holding it just to make sure nothing happened. Sorry this is so vague, do you have any idea what telescope I'm talking about? Keep in mind its not finished yet(I don't think).
The Subaru telescopes is pretty big... But check out this monster... http://news.bbc.co.uk/1/hi/sci/tech/2116605.stm
