Gemini North Shines a Laser

Gemini North telescope, half of the International Gemini Observatory, shines a low power laser into the sky to create a laser guide star. This laser guide star serves as a reference for the telescope's adaptive optics system so that it can 'cancel out' the effect of atmospheric turbulence on the images of its actual targets.
