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.
They have changed because now there is a telescope in space called the "Hubble". I can see things that regular telescopes on Earth cannot see.
it is outside of the atmosphere therefor no atmospheric inerference
It is closer to the stars

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.

Telescopes like the Hubble
Because light is absorbed and disturbed as it passes through air ... effects that ground-based telescopes have to live with but Hubble doesn't.
The Hubble telescope is different from land based telescopes in that being in space it does not suffer atmospheric distortion, thus clearer pictures.
yes
Since the Hubble Telescope is in space, it avoids interference from the atmosphere.
The most serious astronomical research, such as that done by the Hubble Space Telescope, is done with reflecting telescopes.
