This one is designed like the GTC and Keck, so it is made of many mirror segments working together. It is about the same size as Keck, but is of course in the southern hemisphere, so that makes it the biggest single optical telescope south of the equator. While these telescopes are relatively new, the old standard for a big telescope was 4 or 5 meters in size (13 - 16 ft). This used to be the size of the "big" telescopes available for research, but with new mirror design and manufacturing processes, it is possible that 10 meter mirrors will be built in the future. Actually, some people are even working on telescopes with 30 or more meter wide mirrors! Stay tuned for record breakers in the "biggest optical telescope" race over the coming years....
