It used to be that if astronomers wanted to get rid of the blurring effects of the atmosphere, they had to put their telescopes in space. But a technology called adaptive optics has changed all that.
Adaptive optics systems use computers to analyze the light coming from a star, and then compensate for changes wrought by the atmosphere, using mirrors that can change their shapes up to 1,000 times per second. The result: To anyone on Earth peering through the telescope, the star looks like the single point of light it really is.
