The sun and the solar system was formed about 4.5 billion years ago. The solar system originated from a cloud, composed of gas and dust particles moving. Under the influence of its weight of it formed a disk in the center of which formed the Sun .
Gradually within the disk began to form solid materials. They faced each other, whereby a large celestial body. Their size corresponds to the existing planets. Inside the nebulae, where the temperature was high enough to form rocky planets. Far from the center formed the giant planets, they contain a large amount of ice, and they were surrounded by a thick layer of gas.
Within the Solar system the temperature even higher, and planets formed from rocky debris of the solar nebula. They are in contact with each other, forming a large celestial body. They attract each other by virtue of the power of the law of gravity and give birth to planets of terrestrial group. The atmosphere of the Earth and Venus, the largest among them, tight.
The atmosphere of Mars, a smaller planet is less dense, and mercury. the smallest planet of this group, it is very sparse compared to earth is not readily available.
Outside the Solar system,on the contrary, or due to the large number of large heavenly bodies, or because of the excess water formed a huge body, surrounded by natural satellites. Continue reading
Comet Churyumov-Gerasimenko with the module “Fily” reached the nearest point to the Sun
Apparatus “Rosetta” was launched into space in March 2004 with a spaceport in Kourou to study the comet 67P/ Churyumov-Gerasimenko. To the destination apparatus has arrived in 2014 and is currently in orbit around the comet. November 12, 2014 on the surface of the investigated object was launched module “Fily”. He entered the history of space exploration, as the first probe successfully landing on a comet for the first time and managed to drill the surface for the taking of soil samples. Thanks to this unique scientific mission scientists expect to obtain detailed data about the physical and chemical structure of the comet, which will greatly expand human knowledge about the origin of the Universe.
According to him, the closer to the star in recent months, the comet’s activity has steadily increased. This is evidenced by the comparison of Photographs taken by Rosetta, the robot lander with a difference a year last summer and now. Continue reading
Dutch company Mars One intends to send the first volunteers to the Red planet by 2023. But our expert explains why it’s not going to happen
Organizers of large-scale colonization of the red planet have previously determined the volunteers who will fly to Mars by 2023
Organizers of large-scale colonization of the red planet have previously determined the volunteers who will fly to Mars by 2023. Dutch company Mars One is counting on that date for $ 6 billion to build a permanent base there.
Just primary have been selected 1058 candidates. Most of them are residents of the U.S. — 297 people. From Russia – 52 volunteers. But by 2015 the project managers will select 24 people who will go to Mars. By the way, the company warns that a return ticket is not provided.
Deep space is not for fools
