Why are some telescopes placed in orbit around the earth?
because looking through the Earth's atmosphere can distort the incoming light.
The Hubble Space Telescope obtains higher-resolution images than most ground-based telescopes because it is?
Only because it gets no atmospheric interference, which most of the ground based telescopes do.
Why are near infrared telescopes located on mountaintops and ultraviolet telescopes in Earth orbit?
Mountaintops are ideal for near-infrared telescopes because the high altitude reduces atmospheric interference and light pollution. Ultraviolet telescopes are placed in Earth orbit to avoid absorption of ultraviolet light by Earth's atmosphere, which allows for clearer observations of objects emitting in the ultraviolet spectrum.
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?
Telescopes like Hubble produce more detailed images than Earth-based telescopes because they are positioned above Earth's atmosphere, which can distort and blur images. This allows Hubble to capture sharper and clearer images of celestial objects. Additionally, Hubble's location in space enables it to observe wavelengths of light that are absorbed by Earth's atmosphere.

What have scientists learned from telescopes?
They have learned that Earth revolves around the Sun.
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.

Why can infrared telescopes operate from high flying aircraft and high mountain tops whereas Xray telescopes must be place in orbit?
Current telescopes detect different wavelengths of "light," which, in general, is called electromagnetic radiation. Earth's atmosphere is transparent to infrared radiation - it can easily transmit though our atmosphere. Therefore we can easily detect it from within Earth's atmosphere. However, X-Rays do not easily transmit through the Earth's atmosphere, so we must place our X-Ray detectors OUTSIDE of our atmosphere, ie. in orbit around the earth.
Why are big telescopes found on top of mountains?
The Earth's atmosphere provides interference to optical telescopes because the molecules in the air scatter and disrupt light. Many telescopes are placed at high elevation because the atmosphere is thinner and will cause less interference.
Why are telescopes observations better on the moon than on earth?
Observations from Earth-based telescopes are obscured by the atmosphere.
How have telescopes changed since they were invented?
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.

What is an Earth telescope?
An Earth-bound telescope is merely a telescope located on Earth. This term is used to distinguish all of our normal telescopes on Earth from space telescopes or orbiting telescopes. The Hubble space telescope is the most famous space telescope, but there are many dozens of telescopes orbiting Earth which look at Earth or the Sun or other objects in space. Obviously, it is easier to construct an Earth-bound telescope and they can be bigger since getting a telescope into space requires a rocket and a lot more engineering and money. Space telescopes have the advantage of being outside the atmosphere and thus no atmosphere to diminish the quality of the image. For infrared telescopes there is the advantage of being in the cold environment of space where the interference from radiations of hot objects on Earth is absent. On the other hand, space telescopes are hard to repair and you can't really be there to look through them.
