Green beam

In our time, has already cracked the secret of the green sun. The fact that the earth's atmosphere like a huge prism surrounds the entire earth's surface. Passing through it, the sun's rays can be decomposed into multi-colored components. But man can not always see. Expansion of the white light spectrum is especially noticeable when the sun is getting ready to go beyond the horizon. If you look in the telescope at a major star, which is near the horizon, then you will see not a bright white dot, and small multi-colored column. White star turns into an iridescent column. Our eyes are, in essence, is seen not only a white disk of the sun, and a few colored discs. These discs are superimposed on each other and add up to white. The upper edge of our light has a blue and mixed with green color, and lower - red. The sun goes below the horizon for a few seconds and it will disappear from sight. At this point in the sky are only the top edges of two colored disks. But the blue and green beams pass through the thickness of the earth's atmosphere is not the same: green penetrate through it freely, and the blue is strongly scattered and almost to the ground do not reach. At the time of the last moments of the sun and you can see the green tip of the star. If at this moment to look at it in a portable telescope, we can see that the narrow strip of light surrounded by a green halo. In his last moment of the day a great light casts a green light into our eyes. The necessary atmospheric conditions for the emergence of green light are added quite often. It is necessary that the air was dry enough and, most importantly, transparent. Horizon should be clear, no clouds and fogs. It is important that on the horizon, there was no irregularities: forests, mountains, buildings and so on. Such conditions are usually formed on the sea. Watch the sun at sunset is best with some of the hill. A long look at the solar disk can not can damage your eyesight. But when it goes over the horizon is almost entirely and will remain a bright band, look no stopping. And if you're lucky, you'll see not only green, but blue ray. This beam is seen very few witnesses, and so watch the blue ray - a great success. Ancient people believed the appearance of a blue ray an important sign. They thought that it involves big changes in the lives of the people.
