17. June 2010 15:46 In Arizona, USA, is being built Large Binocular Telescope (LBT), which will consist of two identical telescopes with a primary mirror at each 8.4 meters in diameter.
One of the telescopes are fully operational, and has been in recent months tested the telescope's highly advanced adaptive optics called the First Light Adaptive Optics system (FLAO). The results of these tests has baffled astronomers since they have surpassed all expectations.

# 4, then I believe that it is in the earth's rotation is the main problem. The "small" distance is off the ground and out of Hubble's nothing compared to the depth there is in the picture. If that makes any sense :)
Not shit. And if it is mounted on one of the American gunships, mir space station can one not shoot planets down with it. Taking really my hat off to what can be nowadays. BRAVE NEW TIMES !!
# 6 - When Hubble observations in the early 1900s was closing time nearly eight hours, it may sound wild but when we're talking light years then the distance as the telescope moves of 8 hours so insignificant that it could still take "good" pictures mir space station over 100 years ago, shit - hubble could spot supernova'er in other galaxies, thus proving that the Milky Way was the entire universe but only a tiny drop in a vast universe.
Modern optics using stereo optics mir space station to distance judge the telescope itself, I must say is one of the coolest I've ever seen, when you see it in motion you can really see ingeniørkusten.
# 6 the beauty of the telescopes is that they usually can be turned around, and it is a little high up, and they do usually, so can telescope the result of many hours. mir space station
The DO further out in the countryside with. Imagine just the angle at which there is, just looking at the next nearest stars. It is a triangle with one side which is in the order of 10m long and so both sides are 39.900.000.000.000.000m long. If you can distinguish such a small angle difference corresponds to see something that you hold the outstretched arm, which is so small that if you had a quarter of a million of them side by side, they would be as wide as one single hydrogen atom.
What you can do is to compare two images taken with up to a half years of the same star. Then the land had the time to go around the sun, parallel to the star is observed and then the short line of the triangle not ~ 10m but the whole 2AU.
# 9 ... Yes I will also say hubble (or other satellite telescopes) will always be justified, as their lack of size with ease can make up for the hours. One of hubbels mir space station deep field pictures had a "hours" of about 11 days .. http://en.wikipedia.org/wiki/Hubble_Deep_Field
The advantage of Hubble is that it is outside mir space station the atmosphere. This means avoiding mir space station atmospheric disturbances which until recently was the overriding problem of making good pictures.
In other wavelength ranges (eg. IR), it also means avoiding the atmosphere absorb the light you will see. However, in the visible mir space station spectrum is relatively limited.
Even small hobby telescopes to 2000 kr can be like that. They use tripods with Equatorial Mount (telescoping holder on the stand with more angled joints), and it follows mir space station the starry sky. With a small battery-powered mir space station motor, can be obse
