The primary goal of an optic is to gather light and recreate a crisp image. The reason for a large primary objective is to gather as much light as possible to see increasingly more distant objects. Crisp, highly detailed images come from what is called intferometry. This technique takes the output from multiple telescopes great distances apart and passes the data through a supercomputer that combines the image. Intferometers create what's called a "virtual telescope" whose resolution is comparable to that of a real telescope the size of the distance between the actual optics.

What is the best insulation to keep heat out of a building?
The best insulation to keep heat out of a building is reflective insulation, such as radiant barriers or reflective foil insulation. These materials reflect heat away from the building, helping to keep it cool.
If the Hubble Space Telescope works so well why not make a much bigger one and get an even better picture of the universe?
Money, it all comes down to money. The Hubble telescope is a multimillion dollar thing, i think its total cost is in the billions. So imagine what a better one would cost! Plus, the Hubble telescope has been able to do everything we needed it to. So until it can't keep up, i think we will keep good old Mr Hubble.

Telescopes have been sent to space because ground-based telescopes?
I assume the question is why we spend so much money putting telescopes in orbit when we have ground-based telescopes. The answer is because the atmosphere creates a lot of distortions that limits how far our telescopes can see, and what they can see. Astronomers, as all scientists, are explorers; they are not content to keep looking at the same objects with the same level of detail over and over. It is much like the way so many people like HD television over old analog t.v. ... when looking out into space and distant stars, the atmosphere creates distortions and cannot see very well during the daylight (just as you cannot see stars during daylight). The problem is getting worse by the problem of light pollution -- all those security and traffic lights on all night long in cities creates a glow of light that makes stargazing even more difficult, even at night. By putting telescopes into space, they are no longer hindered by atmospheric distortions and are unaffected by light pollution from our cities. A telescope in space versus on the ground is analagous to an H.D. television versus an old analog t.v. -- there is much more you can see, and what you can see is in greater detail.

What is freehold building?

Why do we keep some telescope in space?
In space, however, telescopes are able to get a clearer shot of everything from exploding stars to other galaxies. Another disadvantage for ground-based telescopes is that the Earth's atmosphere absorbs much of the infrared and ultraviolet light that passes through it.
