Thirty Meter Telescope
Caption: The two W. M. Keck Telescopes on Mauna Kea, Hawaii, observing the galactic center. The lasers are used to create an artificial star in Earth's upper atmosphere, which is then employed to measure the blurring effects of the lower atmosphere (the unfortunate effect that makes the stars twinkle in the night sky). The blurring gets corrected in real time with the help of a deformable mirror. This is the so-called adaptive optics technique.
