The Hubble's main advantage is that it doesn't have the distorting effects of atmosphere to cope with. Also, because of its perfect seeing conditions, the Hubble was built to a higher optical standard than most large Earth-based telescopes.
Large telescopes such as the VLT can exceed Hubble's resolution using adaptive optics. At present, though, this technique only works over a very small field of view.

Tiny gremlins in the Hubble can focus the lense much more clearly than on the earth. That is the only explanation.
Sorry, I just got done answering a question in the paranormal section of Science and Mathmatics and was trying to apply their leaps of logic about ghosts and aliens to this question.
I could be wrong.

Distortion is a big problem with earth based telescopes,because of our atmosphere,in space, other than minute dust left over by the big bang or passing comets,there is no haze caused by the atmosphere

It has no atmospheric distortion to contend with. It also can remain fixed on an object for many, many hours - or days, even - without worring about the Earth's rotation carrying the object out of view.

it has to do with atmospheric distortion. ground based telescopes, no matter the size, have to deal with it. hubble avoids the problem all together. the link below should help you with more details. http://hubblesite.org/the_telescope/hubble_essentials/

Because it doesn't have to deal with 60 miles of atmosphere, which distorts images of terrestrial telescopes.

Because it does not have to deal with refraction caused by the earth's atmosphere.

It is in space, and thus doesn't have to look through the hazy atmosphere.

doesn't have to see through pollution and atmosphere
