P About H E M The H To And


You already know, why on Earth the sky is blue because the atmosphere of the earth most strongly scatters the blue part of sunlight. What is the sky on the other planets of the Solar system?

On the moon, and mercury and Pluto the atmosphere there. Nothing reflects light rays. So the sky on the moon is black. And bright stars twinkle.

On Venus the sky is yellow with grayish tinge on the horizon, and orange at the Zenith. Because the atmosphere of Venus absorbs blue and green rays of sunlight, and those rays that manage to pass through the atmosphere of Venus, giving the sky a shade.

On Mars, the sky is yellow-orange, but not because the atmosphere of Mars stronger scatters red rays, but because the atmosphere of Mars is a lot of dust. And it is reddish in color. During sunrise and sunset the Martian sky at the Zenith has a reddish-pink color, and in close proximity to the disk of the Sun from blue to purple. Exactly the opposite pictures of the sunset and sunrise on Earth!

Noon on Mars. Sunset on Mars.

The sky of Saturn blue, as on Earth. And the Cause of the blue sky on Saturn is exactly the same as on Earth.

On Uranus , the sky has a beautiful aquamarine color. The reason for this lies in the composition of the atmosphere of Uranus and its temperature. In the upper hydrogen-helium atmosphere is constantly present methane haze. Methane absorbs red light, and reflects blue and green. So the sky Uranium has a beautiful aquamarine color.

On the Neptune less hydrogen and helium, but the methane gas in the atmosphere absorbs red light. As a result, the sky at Neptune blue.

On Jupiter all the cloudy days. Jupiter has no solid surface, it is a gas giant. Gas, of which it consists, simply gets denser with depth. And at the top it forms a solid, dense clouds. The color of the clouds change with height: the bottom of the cloud blue, then brown, and white and finally red -- the top. Sometimes you can see the lower layers through the holes in the top. This three-dimensional image shows a simplified view of what you can see from between the layers of the clouds on Jupiter. The picture is based on the data obtained by the cameras of the spacecraft Galileo.

The upper grey layer is a fog thickness of several tens of kilometers.

It is logical to assume then, that if in the sky of Mars so much dust that the sky is brown, and the visibility was not more than 1 cm Else would like a fog. Which in fact is not observed.

Full of crap. NASA specifically hides the true colors of the planets ...
