The origin of the solar system
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. Continue reading
Why Just the ninth planet in the Solar system, according to the International astronomical Union (IAU), there are eight planets. Pluto the IAU decision in 2006 is no longer considered a planet by going to the class of dwarf planets because it is not dominant in its space orbit. According to scientists, the Solar system may be over two thousand dwarf planets. However, the definition of a planet as a dwarf is still a matter of controversy. In particular, a crucial role may play the size of a celestial body.
Therefore, to say that discovered ninth planet in the Solar system very early.”
The scientist reminded that beyond the orbit of distant planets in the Solar system has many objects that are studied by astronomers. Among them was discovered a new heavenly body, which claims the title of planet in the Solar system.
According to the authors, it is a gas giant with a mass of 5-10 times the mass of the Earth. This planet supposedly moves in an elliptical orbit, making a complete revolution around the Sun for 10-20 thousand years. According to the calculations of astronomers to confirm the planet’s existence by observation through the telescope, will take several years. Continue reading
It turns out that people have learned to make interstellar travel over huge distances. Previously it was thought that use gravity for space jump can only sverhrazdutoe of civilization, as fuel is always limited — it is impossible to bring as much as you want. However, science has leaped forward. Not everyone knows about what happened is a real space revolution.
This principle, the flights with the help of gravity, demonstrated in the sensational film “interstellar”. Read more about this amazing phenomenon tells Kip Thorne, a theoretical physicist, consultant to the film (he invented everything that has to do with science) and the author of the book “interstellar. The science behind the scenes” .
The view from the ship, performing a gravitational slingshot
Though Director Christopher Nolan decided not to show the gravitational slingshot (maneuvers, which we describe below) in “interstellar” Kip Thorne was curious, as if they saw Cooper, the main character, piloting the “Ranger” to the planet Miller. So he is using his equations, modeled images for a camera that would Record with the Ranger, making the maneuver around the black hole before landing on planet Miller. Continue reading
