DescriptionBackground Information- Laser Guide Stars (gemini0504c).jpg |
English: At about 50 miles above the Earth’s surface, the yellow/orange laser light encounters a layer of sodium in the upper atmosphere and the light causes the molecules of sodium to glow as seen from the side. This artificial guide star allows continuous assessment of how the atmosphere is distorting starlight passing through the column of air that the telescope is observing through. |
