O.T. i didn't know they were building this..

The picture shows the size comparison to current telescopes .Will be built in Chile . The telescope's "eye" will be 39.3 meters (about half the length of a football pitch/soccer field) in diameter and will gather 15 times more light than the largest optical telescopes operating at the time of its development. The telescope has an innovative five-mirror design that includes advanced adaptive optics to correct for the turbulent atmosphere, giving exceptional image quality.[11] The main mirror will be made up from almost 800 hexagonal segments.[15]

The primary mirror for the 39.3 metre design will be composed of 798 hexagonal segments, each 1.45 meters across but only 50 mm thick. A special correcting mirror in the telescope will be supported by more than 6,000 actuators that can distort its shape a thousand times per second.[16] The telescope main structure will weigh about 2,800 tons.[17]

[edit] Science goalsThe E-ELT will search for extrasolar planets — planets orbiting other stars. This will include not only the discovery of planets down to Earth-like masses through indirect measurements of the wobbling motion of stars perturbed by the planets that orbit them, but also the direct imaging of larger planets and possibly even the characterisation of their atmospheres.[15] The telescope will attempt to image Earthlike exoplanets, which may be possible.[2]

Furthermore, the E-ELT's suite of instruments will allow astronomers to probe the earliest stages of the formation of planetary systems and to detect water and organic molecules in protoplanetary discs around stars in the making. Thus, the E-ELT will answer fundamental questions regarding planet formation and evolution and will bring us one step closer to answering the question: are we alone?[4]

By probing the most distant objects the E-ELT will provide clues to understanding the formation of the first objects that formed: primordial stars, primordial galaxies and black holes and their relationships. Studies of extreme objects like black holes will benefit from the power of the E-ELT to gain more insight into time-dependent phenomena linked with the various processes at play around compact objects.[15]

The E-ELT is designed to make detailed studies of the first galaxies and to follow their evolution through cosmic time. Observations of these early galaxies with the E-ELT will give clues that will help understand how these objects form and evolve. In addition, the E-ELT will be a unique tool for making an inventory of the changing content of the various elements in the Universe with time, and to understand star formation history in galaxies.[18]

One of the most exciting goals of the E-ELT is the possibility of making a direct measurement of the acceleration of the Universe's expansion. Such a measurement would have a major impact on our understanding of the Universe. The E-ELT will also search for possible variations in the fundamental physical constants with time. An unambiguous detection of such variations would have far-reaching consequences for our comprehension of the general laws of physics.[18]

I only hope we have no USA tax money invested. I know knowledge is priceless, But the knowledge this gleans will not reduce our deficit or increase the strength of our currency. JMHO gobble
 
I personally think its great I have a program on my I-pad that tells me when a new planet is found its fascinating to some of us.

If we aren't already paying for it the U.N. can add to their tax on the internet and get us that way.
 
They won't show themselves until then - they'll be around watching before then tho....

I got a neighbor who is an actual astronomer. A real live scienist. He hates to see me coming cause he knows I will ask about stuff like this... and the lodge must not tell the secrets of the universe.... like the cold war, news media tells us one thing, truth is somewhere inbetween.
The first to let the cat out of the bag was the Vatican, in the mid 80's, building a huge telescope on the south pole, aimed straight up.
The southern hemisphere is getting alot of stuff like this the last 20-30 years...they say cause of clear skies and no lights etc- but really cause the brains want to look directly south.... like where all the 'near earth objects' are coming from. They think there is alot of space junk- meteors, asteroids etc- hopelfully nothing bigger- coming closer and more often, from due south... but we the people might get frightened.... so they come up with stories about ET's and life on other planets, so we go away thinking it is just more wasted tax dollars... people sleep easier thinking along those lines...
