Summary
[edit]DescriptionGemini South's Laser Guide System (summit nights-79-CC).tiff |
English: This photo shows Gemini South's laser guide star system in action. The laser interacts with particles in the Earth's upper atmosphere and allow for real-time corrections of the telescope's optics to compensate for atmospheric turbulence. Gemini South is a part of the International Gemini Observatory, a program of NSF's NOIRLab. The Magellanic Clouds are also visible in the direction the laser is aimed in this photo. |
