World's Largest Telescope

AKA Rommie's next big adventure... Exploring the Chilean high desert while studying the stars.

As de Zeeuw said, E-ELT is not the only giant ground-based telescope in the works. The Giant Magellan Telescope (GMT) will soon start taking shape atop Las Campanas, another Chilean peak. GMT will arrange seven 27.6-foot-wide (8.4 m) primary mirrors into one light-collecting surface 80 feet (24 m) across; project officials are aiming for "first light" in 2021.

And the Thirty Meter Telescope (TMT) — which, not surprisingly, will boast a light-collecting surface 30 m, or 98 feet, wide — is slated to start observing from Hawaii's Mauna Kea in 2022. Like E-ELT, TMT's primary mirror will be composed of hundreds of relatively small segments.

All three megascopes should help researchers tackle some of the biggest questions in astronomy, including the nature of the mysterious dark matter and dark energy that make up most of the universe.

Yeah, I'm not an optical astronomer, but have some buddies who have been involved and are quite excited.

Always fun to read about this stuff.
