Topic is The clouds of planets.

 

Do you know it? You know that there is a cloud on the earth well, but, in fact, there can be a cloud in the space! There is the cloud on other stars except the earth. I introduce the cloud of the space this time.

 

 

The cloud of the space is called cosmic cloud and nebula. Nebula is gas consisting of the gas between cosmic dust and the stars who had a unity gravitationally drifting in the outer space. The space is a vacuum. Something like cloud floats there. The cloud is crowd of the gas (most hydrogen). The gas of the cloud of a one-1,000,000,000th of the air of the earth the; is very thin with a one-1,000,000,000th again. However, when there is thickness as for dozens of light-year, it catches the light of the star and shines and cover the star in the background and I can watch it. The gas cloud becomes the materials of the star. The particularly deep place of the gas cloud is called a molecular cloud, and a star becomes the born place. I was surprised. The earth seemed to be made in this way, too!!

In addition, a star runs out of life when leading fuel empties. The surface gas of the star opens steadily and becomes the round nebula. The nebula glitters in various colors by the light of the small star who stayed in the center, but the nebula is scattered to the space before long and disappears. The nebula gives birth and the death of the star to us!!

 

 

 

Cloud of other planets
I introduce the cloud of the star except the earth.

 

 

Mars

In the Martian atmosphere, very few steam is included. The steam pressure is only around a one-500th of the South Pole sky of the earth, but a cloud and frost are observed on Mars by these very few steam. The Martian cloud appears in the early morning and the evening and disappears in the daytime. NASA confirmed snow on Mars!

 

 

 

 

Jupiter

The Jupiter is always covered by a cloud, and the surface observed by visible light is the outer layer of the cloud not the ground. It is thought that this cloud was made with a crystal and an ammonia hydrosulfide of the ammonia. In addition, this cloud accumulates energy of the thunder. This electric discharge phenomenon is equivalent to 1,000 times of the lightning of the earth; is large!!!! The reason why a cloud is orange and brown. It is that the compound which welled up from the inside changes in quality by solar ultraviolet rays and changed a color.

 

 

 

The Saturn

The surface is the same as Jupiter, and most are made of hydrogen and helium. The atmospheric thickness of the Saturn is 1,000km, and the half is a layer of the thick atmosphere. It is the lowest planet of the density in the solar system. If there is the huge ocean, the Saturn seems to float!

 

 

 

 

 

 

 

I examined a cloud of the space and knew that an ingredient was different from a cloud of the earth. The cloud of the space is mysterious. I want to watch them with my eyes.
