Mostly, it doesn't. The only time the Shuttle is in the atmosphere is for about 3 minutes on launch, and most of the exhaust is water vapor.
Most spacecraft that leave orbit and reenter the atmosphere burn up, but this does not contribute much in pollution unless nuclear material makes it to the surface.
The greatest hazard created is that orbital space is now cluttered with debris, making it a more dangerous place to go.
The earth's atmosphere causes star light to shimmer and blur due to the motion of the air above the telescope. The atmosphere filters out a lot of the light. This is why the big observatories are up high e.g. in the Andes. The air is thinner (i.e. less atmosphere), so the stars are brighter and the air clearer.
The biggest problems that astronomers face, as scientists, is that they CANNOT do repeatable experiments. They can't (yet!) build a star from scratch and observe its entire life cycle, or perform any real tests, or even go there and perform close-up observations.
Everything that they do is simply observing, from here.
It doesn't effect them; it affects them.The atmosphere absorbs part of the light that goes through it. The main problem, however, is that the atmosphere is moving about all the time; this results in changes (due to small-scale refraction), which severely affect the image quality, compared to a space-based telescope.
Observations from Earth-based telescopes are obscured by the atmosphere.
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.
because looking through the Earth's atmosphere can distort the incoming light.
Radiation other than light and radio waves hardly penetrates Earth's atmosphere.
Earth's atmosphere does not limit a telescope's resolving power.

Telescopes on Earth have to look through the atmosphere (air) which distorts the image. Telescopes in space dont have to look through the atmosphere and so the image is a lot clearer.

The main advantage is that it avoids distortion from Earth's atmosphere.

The earth's atmosphere doesn't let these rays reach the ground, so the telescopes are placed in orbit where they can receive the rays.

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.
