By projecting a powerful laser beam into the night sky, researchers at the Lawrence Livermore National Laboratory can create an artificial star. When viewed through a telescope the artificial star appears blurred due to winds in the lower atmosphere distorting the light. If the artificial star is positioned next to an object that the astronomers wish to study and then both objects observed using a telescope with a flexible mirror, a computer can be used to bend the mirror until the artifical star looks sharp. Since the artificial star has suffered the same distortion as the object in space a pin sharp image of the object can now be obtained.
