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
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
April 12 (cosmonautics Day) is one of the outstanding dates in the history of the world. It is in this auspicious day super booster successfully launched into orbit the first ever space ship “Vostok-1” with the first cosmonaut, a citizen of the Soviet Union, Yuri Gagarin.
“Man is ever weary of the country in which he lived, and tried his best to push. The desire for the Unknown, to the knowledge of what was outside of his native place — the home, the field, the planet has always been one of his most powerful feelings”.
Cosmonautics day — a memorable date, celebrated on April 12, installed to commemorate the first manned flight into space, it is a celebration of the human mind, of intelligence.
Unknown to the mankind was Space. But in 1957 changed everything. “The beginning of the Space age marked by the launch on 4 October 1957 the first Soviet artificial satellite of the Earth. News of the launch of the satellite inscribed in Golden letters in history”.
“The space age… With these words, the majority of the inhabitants of the Earth are related some concrete representation”. Meanwhile, the history of Space exploration is to our eyes. Continue reading
