At sunset, at the moment when the Sun disappears from view, you can see the green light. The green beam, as it is called is an optical phenomenon caused by refraction in the atmosphere. Shorter waves are more strongly refracted than the longer red waves, separation of colors gives a green tint to the last visible remnant of the upper part of the solar disk (bottom disk is red).
The idea is that the sun should be purple, but these rays — the most high, in the atmosphere they are scattered, besides, the human eye is less sensitive to them. So with the last light and turns bright green.
Is it possible to see the emerald beam of the moon or even Venus, and mercury? With the help of camera and lens — Yes.
In this image, a few pictures, they were all made in Sicily. The sun was photographed on March 18, 2019, Luna may 8, 2020, and Venus and mercury — may 24.
