VLT Laser Guide Star joins the night sky
The Laser Guide Star (LGS) is launched from the VLT's 8.2-metre Yepun Telescope and aims at the centre of our Galaxy, in the heart of the brightest part of the Milky Way, creating an artificial star in the Earth's mesosphere. This star is used as reference to correct images and spectra.
