Venus, Mercury after the closest planet to the Sun and the brightest in the sky at dawn to reflect much of the sunlight star.

In the picture you can see it happening right in front of the sun, just when you can study its atmosphere, composed primarily of carbon dioxide through the light that pierces.

The atmosphere of Venus is very interesting as it is dense nose apart from containing some very strong winds to the solar system.

Is so dense that the pressure is very high (about 100 atmospheres, a bit silly) probes sent there have not lasted long running (hours). Come on, it’s almost like a soup.

The clouds of the planet, due to pressure (yes, I will insist that it is high) are not formed as here, by convection of the atmosphere existing water (you know rises it cools, condenses, falls, heated, it evaporates, rises) but by chemical reactions of sulfur and water.

The wind, because of the atmosphere, a soup, is “strange” for what we have here, moving slightly on the surface but reaching high speeds in the upper layers. This has been called “super rotation” as the winds can turn around the planet in a few days (3 or 4 if I remember correctly).

As Venus has no auroral magnetosphere, which means that the core is cold and movement (soup) of its atmosphere generates nothing unlike Neptune, the talk yesterday. And with no magnetosphere, solar wind sweeps the atmosphere and carries, similar to what happens on Mars where process, even having magnetosphere is so weak that its atmosphere has been lost due to solar shock.
