What primary technical limitations of Earth-based observation necessitated placing telescopes into space?

Answer

Atmospheric distortion, light pollution, and absorption of certain wavelengths.

Observing from Earth is hampered by atmospheric distortion and pollution, as well as the atmosphere's absorption properties, which necessitated placing instruments like the Hubble Space Telescope above the atmosphere for greater clarity.
