Distortions in the atmosphere such as turbulence and wind shear create those twinkling effect we see while stargazing, but when you look through a telescope, there's no twinkle—just a big blur. Lately, a growing group of vision scientists have turned to a solution pioneered by astronomers—adaptive optics, originally developed by the military and used by astronomers..
