Thirty Meter Telescope...

It looks like it's really going to be built, on Mauna Kea in Hawai'i

Not so very long ago, the largest telescope in the world was the Hale Telescope, here in San Diego on Mt. Palomar.  That telescope is still in operation, 200" in diameter – a light-collecting area of about 20 square meters.  The Thirty Meter Telescope is 30 meters in diameter, giving it a light-collecting area of about 707 square meters – over 35 times bigger than the Hale Telescope.
