New Telescope To Make 10-Year Time Lapse Of Sky

Originally published on Fri January 10, 2014 3:30 pm

The Large Synoptic Survey Telescope, seen in this artist's rendering, will be built on the peak of the Cerro Pachon mountain in Chile and will survey every patch of the night sky. The data the telescope will collect will allow researchers to "answer fundamentally different questions about the universe," says one astronomer.

Every 10 years, about two dozen of this country's top astronomers and astrophysicists get together under the auspices of the National Research Council and make a wish list. The list has on it the new telescopes these astronomers would most like to see built. At the last gathering, they said, in essence, "We most want the Large Synoptic Survey Telescope."

Here's why. A synoptic survey is a comprehensive map of every square inch of the night sky. The Large Synoptic Survey — LSST — will do that multiple times.

Scientists can spend years working on problems that at first may seem esoteric and rather pointless. For example, there's a scientist in Arizona who's trying to find a way to measure the age of wild mosquitoes.

As weird as that sounds, the work is important for what it will tell scientists about the natural history of mosquitoes. It also could have major implications for human health.

One week after pausing with about 40 feet to go, Russian scientists today announced that they have successfully drilled through two miles of ice to reach Lake Vostok — a body of water the size of New Jersey that hasn't been touched for millions of years.

The world's largest mirrors for the world's largest telescopes are made under the football stadium at the University of Arizona.

Why there? Why not?

"We wanted some space, and it was just used for parking some cars, and this seemed like a good use," says Roger Angel.

Angel is the master of making big mirrors for telescopes. For 30 years he has been using a method called spin casting to make the largest solid telescope mirrors in the world.
