There is less air above the telescope, so there is less interference from the atmosphere. Space telescopes avoid such problems completely since they orbit outside the atmosphere. Q: Space telescopes avoid such problems completely since they orbit outside the what? Choices: - ozone layer - galaxy - earth's crust - atmosphere A:
