Mostly because of atmospheric abberations. Our air is constantly moving and has different layers of hot and cold air. This causes light waves to bend and make images from space appear distorted. This is also what makes stars twinkle.
Mainly visual and radio. But there are Xray, UV and IR.
Telescopes that work grounded on Earth include optical telescopes, radio telescopes, and infrared telescopes. However, space telescopes, such as the Hubble Space Telescope, do not operate from the Earth's surface. Instead, they are placed in orbit to avoid the Earth's atmosphere, which can distort observations.
Observations from Earth-based telescopes are obscured by the atmosphere.
Radio signals are sent from Earth, to operate the 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.

X-ray telescopes are used to study mainly the Sun, stars and supernovas. X-ray telescopes work better at very high altitudes on the Earth's surface.

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.
