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.
Do astronomers use ground-based X-ray telescopes?
No they do not, or use gamma ray telescopes either. Not ground based.
What do astronomers use to look at planets?
Their eyes, ground-based telescopes, space telescopes.
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

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 do scientists use to study the Earth from far?
Satellite-based telescopes and sensors.
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.
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.
What is an advantage of using orbiting telescopes rather than ground based telescope?
There is no distortion from Earth's atmosphere.
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.
Why can hubble space telescopes see much further into space and product much clearer images then telescopes on earth?
Because light is absorbed and disturbed as it passes through air ... effects that ground-based telescopes have to live with but Hubble doesn't.

Why are astronomical IR telescopes deployed well above the cloud but never on the ground?
Ground based telescopes are not as effective at these observations because infrared light is largely blocked by water in Earth's atmosphere.
Do astronomers use ground-based X-ray telescopes?
No they do not, or use gamma ray telescopes either. Not ground based.
