Adaptive optics which change the shape of large mirrors during observation have helped to reduce atmospheric distortion.

Why are telescopes observations better on the moon than on earth?
Observations from Earth-based telescopes are obscured by the atmosphere.
Why should telescopes such as Hubble produce more detailed images than Earth based 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.
Why are some telescopes launched into space?
Some of the best telescopes are in orbit because the earth atmosphere distorts the light from distant stars,which is something scientist and astronomers would rather avoid.
Why do astronomers put telescopes in space?
The Earth's atmosphere is about 120 miles thick and anything we see from the surface of the Earth is distorted by the water vapor and debris that is in the air. If you are in space you do not have this distortion. The Hubble Telescope is a good example of space based telescopes.Scientists have put telescopes in space to avoid interference by the atmosphere.SOURCE:-Page 560 of Holt Science & Technology Earth Science-Chapter 18-Studying Space-Section 2- Telescopes-Optical Telescopes in Space
Why are optical space telescopes able to see deeper into outer space than land based optical telescopes?
because they are above the Earth's atmosphere
What kind of problems or developments do astronomers face?
One of the biggest problems facing astronomers is that they are Earth based and can not travel with anything besides their eyes and high powered telescopes through space to the stars and planets they study. More advances are being made every day, however, and by the time space travel becomes common our astronomers will have armed us with a wealth of knowledge.
Why do astronomers currently prefer orbiting telescopes over earth based telescopes?
Orbiting telescopes are located in the sky, where it is not affected by the turbulence of the atmosphere, while ground-based telescopes are located on the ground, where the atmospheric turbulence (the moving of air) is greater. This is also the reason that some telescopes are built on mountains where the atmosphere is thinner and turbulence is smaller.

Will New technologies allow astronomers to use X-ray telescopes on Earth's surface?
We had best hope the answer is 'no'. In order to use x-ray telescopes effectively from the earth's surface, you'd have to get rid of the atmosphere.

Can Earth-based telescopes can detect all forms of light?
No. Many frequencies of light are absorbed by the atmosphere, and so Earth-based telescopes can't detect it. That's why space telescopes such as the Hubble are so valuable; they allow us to see in frequencies that we cannot detect here on Earth.
What instrument to look at the sun?
Solar telescopes are used by professional astronomers both on earth and on satellites. These instruments differ from other optical telescopes because they do not need to collect light and also must deal with the heat from the object they focus on. The telescopes are very large.
What do scientists use to study the Earth from far?
Satellite-based telescopes and sensors.
Why have astronomers built the largest optical telescopes on the top of mountains?
To get above the thickest part of the Earth's atmosphere. The air absorbs light and its movements distort the image.
Ultraviolet wavelength telescope to look at distant galaxies?
For Earth-based telescopes this is not a particularly good idea since the ozone layer in the Earth's atmosphere absorbs some of the UV radiation. For space based telescopes, all wavelengths are useful.
