Why is it an advantage to have the hubble telescope outside the earths atmosphere?

Answer 1

One of the reasons why most Earth telescopes are at the tops of mountains is that the air isn't perfectly transparent. It shimmers, it shakes, it distorts the viewing of stars and planets. Even at the tops of mountains like Mount Palomar, Kitt's Peak, or Moana Kea, there is enough air to distort the view.

In space, there is no air. Viewing conditions are always perfect, there is never any haze or rain, and it doesn't matter if it is day or night; the stars and other planets are always perfectly in view.

Answer 2

Having the Hubble telescope outside Earth's atmosphere eliminates the distortion caused by atmospheric turbulence, resulting in clearer and sharper images. This allows Hubble to capture more detailed and high-resolution pictures of distant celestial objects. Additionally, being in space provides an unobstructed view of the universe in various wavelengths of light, which would otherwise be absorbed or scattered by Earth's atmosphere.
