Edwin Hubble
It is closer to the stars
The problem with ground based telescopes is that the atmosphere distorts images, The Hubble space telescope is above the atmosphere and therefore can view with much better clarity.
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.
Hubble does not have to contend with the atmosphere of the earth which bends and distorts images from earth-based telescopes.

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.
All major astronomical telescopes are equipped with spectrographs, including the Hubble and Spitzer Space Telescopes.
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.
The Hubble spacecraft has found more anbout the stars and planets more clearly then the others saw from other telescopes.
Telescopes are used to see things that are far away from earth. Using telescopes we can see things that are millions of miles away. Most of the telescopes are on Earth but some of them are in space such as the Hubble Space Telescope.
The Hubble and Keppler space telescopes are detecting exoplanets
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.
The Hubble telescope is different from land based telescopes in that being in space it does not suffer atmospheric distortion, thus clearer pictures.
