Back in 1672 Newton’s reflector telescope enabled astronomers to get their first clear view of our solar system. But to see deeper into space, engineers building the 183cm Parsons telescope (Leviathan of Parsonstown) in Ireland must learn how to make bigger mirrors. The Large Binocular Telescope (LBT) uses two huge mirrors each measuring 840cm in diameter, making it the world’s largest optical telescope (by effective optical aperture).
Clip from the “Big Bigger Biggest” documentary series exploring the engineering breakthroughs that have enabled us to develop some of the largest structures in existence.
