Constant imaging of high-altitude atoms excited by the laser -- which appear like an artificial star -- allow astronomers to instantly measure atmospheric blurring . This information is fed back to a VLT telescope mirror which is then slightly deformed to minimize this blurring. In this case , a VLT was observing our Galaxy's center , and so Earth's atmospheric blurring in that direction was needed.
