There is no distortion due to twinkling, glow from the sky or the effects of light pollution. A list of space telescopes. In 1946, Lyman Spitzer, a professor and researcher at Yale University, argued that a space telescope would offer great advantages over ground-based observatories. Ground-based telescopes can't do the same, because the Earth's atmosphere absorbs a lot of the infrared and ultraviolet light that passes through it.
