SANTIAGO, Chile (AP) — Astronomers in Chile are blasting away the top of a mountain to install what they say will be the world's largest optical telescope.

The 9,800-foot (3,000 meter) Cerro Armazones mountain will be the new home of the European Extremely Large Telescope.

Thursday's blast is being overseen by officials at the European Southern Observatory in northern Chile.

Their ground-based telescope has a 128-foot (39-meter) mirror, and the astronomers are calling it "the world's biggest eye on the sky." They say it will help advance the study of planets around other stars, dark matter and supermassive black holes.

World's Biggest Telescope to be Installed Atop Chile's Cerro Armazones

The world's biggest telescope is all set to be installed atop the 3,000 metre high Cerro Armazones in Chile after blasting off a significant portion of the mountain's surface.

The European Extremely Large Telescope (E-ELT) project is the brainchild of the European Southern Observatory (ESO), a Britain-based organisation.

According to a Guardian report, the blasting off of the mountain will take place at 2pm local time (7pm BST) on 19 June. This will be followed by month-long operations to clear the rubble after which work for installing the telescope will begin.

A massive, 2,500 tons of steel is expected to be used in building the E-ELT's most important mirror.

The E-ELT will aid stargazers and scientists in a big way. "I feel excited. We are opening a highway for the future knowledge of astronomy," Roberto Tamia is quoted as saying by the Guardian.

Atacama is extremely dry, probably a good idea for delicate equipment. Heres the hope it turns out useful.

5. Blowing the tops off mountains isn't something one can warm to, that's for damned sure.

We've seen more than enough of that already.

The Atacama desert is the driest place on earth, so there's no doubt about the benefits there for keeping equipment in great condition, if they can keep out the dust!

6. At that altitude, dust is probably not a problem..

They go there because it's dry, not so much for the equipment as for the visuals. Water vapor can be really bad for taking photos and stuff. So, think thin air and minimal water vapor to distort images.

Oh, and it's isolated from major light sources like cities, etc.

Dust is bad but nothing can be as bad though as the Hubble at first, remember ? I still remember a cartoon that had a drawing of the Hubble with a pair of giant glasses on, because they had cut the glass wrong or something. Couldnt see anything.
