Показать описание
On 14--16 December 2012, the Geminid meteor shower made a spectacular appearance over ESO's Paranal Observatory in Chile. As the meteors showered down over the site, ESO Photo Ambassador Gianluca Lombardi was ready with his camera to record the spectacle. He spent over 40 hours recording the shower.

The Geminids is a shower of shooting stars appearing to emanate from within the constellation of Gemini (The Twins). This shower occurs when the Earth cuts through the orbit of an asteroid named 3200 Phaethon, which happens once each year, in December. Particles in the trail of dust along the orbit of Phaethon burn up in our atmosphere, creating the brilliant, fast-moving points of light characteristic of meteor showers.

This is for adaptive optics. Sodium laser beams are used to create an artificial star about 80km in the upper atmosphere. They use the artificial star for computers to calculate atmospheric turbulence and in real-time, cancel out distances so they can get the best resolution possible. You can google Adaptive Optics and Lase guide stars - cutting edge stuff!
