VLT laser guide star

The fourth Unit Telescope ESO's Very Large Telescope (VLT), also known as Yepun, is seen here launching its powerful laser beam into the night sky. This creates an artificial star in Earth's mesophere, which acts as a reference for the VLT's adaptive optics system and corrects for atmospheric turbulence.
