it is outside of the atmosphere therefor no atmospheric inerference
There are no clouds, air, dust or anything at all in the way.
Hubble does not have to contend with the atmosphere of the earth which bends and distorts images from earth-based telescopes. http://wiki.answers.com/Q/Why_does_the_Hubble_Space_Telescope_give_clearer_images_than_those_from_earth
Hubble does not have to contend with the atmosphere of the earth which bends and distorts images from earth-based telescopes.
Even in excellent weather, telescopes on Earth are affected by the thickness of the atmosphere. This causes the air to be slightly refractive, meaning that the air bents the light as it comes through the atmosphere, and distorts the image that we are trying to see.The Hubble Space Telescope is much smaller than many terrestrial telescopes, but because there is no atmospheric distortion, the images can be far clearer and can be magnified more.
The hubble is better because it has a camera.
Since the Hubble Telescope is in space, it avoids interference from the atmosphere.

Earth based telescopes have to see through the atmosphere and all the dust it contains. space telescopes like Hubble have nothing but clearspace to see through.
There is minimal atmospheric disturbance up where the Hubble orbits. Down here on Earth we have to contend with the atmosphere.

It is speacial because It can observe the heavans much better than ground telescopes. It is also the largest and most versatile space telescope

There are a few reasons. When you watch the stars at night, you’ve seen how they twinkle. This is because of atmospheric distortion, and that really hampers the ability of telescopes on Earth to get clear images. Since the Hubble is above the atmosphere, it isn’t affected by atmospheric distortion - for Hubble, the stars don’t twinkle. Another reason is that Hubble doesn’t have to contend with light pollution. Telescopes are places in areas where they sky is affected as little as possible by light, but there’s always some light. Another is that Hubble can take very long exposures. Telescopes on Earth are limited to observations at night, but Hubble can take very long exposures, and can observe an object indefinitely.
