It will also have adaptive optics that will allow it to have incredible resolution power. If it is completed in time, in 2022, it could be the first of the new generation of Extremely Large Telescopes.
The primary mirror will consist of 492 smaller mirrors that will be precisely mounted and placed in proximity with each other to give the surface area of the 30 meter telescope. Continue reading Telescopes Of Incredible Size – The Thirty Meter Telescope
