Space: Science and technology

“It’s huge”

About the discovery of the ninth planet of the Solar system two astronomers from the California Institute of technology in Pasadena became known on January 20. One of them — the native of Russia Konstantin Batygin — spoke about the search for Planet X, the difficulties with the title the new heavenly bodies and unsolved mysteries of the Solar system.

What is an open planet?

Konstantin Batygin . She falls into the category of dwarf planets. This celestial body is quite massive. Our model gives a mass of about ten earth, this planet is just a giant. Now it is defined as a celestial object whose gravitational field is dominant in that part of the Solar system.

In General, there is not even a question: it’s a planet or not. We know about it, because its gravity affects the orbit of the farthest objects in the Kuiper belt. The very mathematical modeling relies on the fact that this planet has enough mass for gravity to dominate in the Solar system. Continue reading

The history of Chinese Astronautics

Actually, I got my hands on a smartphone that fully supports navigation using the Chinese navigation system of the Big dipper). On the market, these smartphones should be out in mid to late 2014, but that’s not it.

I thought about how this system works, who and what drove these satellites into orbit and decided to write a brief overview of the history of Chinese Astronautics. Anyone interested — welcome under kat.

Why does the Chinese space program is called chiconautla? Do not suffer, the people of Thailand and Taiwan is not to blame. Just on the Chinese space sounds like (Taicang), which translated means “Too empty”.

The date of birth of the Chinese space can be considered on 16 November 1957. It is in this day was founded by (China national research Institute on rockets) .

Then, of course, he looked a little different.

It has long been observed that the nuclei of periodic comets are depleted, with every turn they glow weaker. Not once was there a division of cometary nuclei into two parts or more. This destruction produced or solar tides, or collisions with a meteor shower. The comet, discovered by the Czech scientists Bilim (Biloy) in 1772 was observed with repeated returns with the seven-year period. In 1846 its core collapsed, and it turned into two weak comets, which after 1852 was not observed. When in 1872, according to the calculations, the missing comet should pass near the Earth, there was rain of “falling stars”. Since November 27 this phenomenon is repeated every year, though less effectively. Small solid particles of the disintegrated nucleus of a former comet Bilogo stretched along its orbit, and when the Earth crosses the stream, they fly in the atmosphere and evaporate. A number of other meteor showers.

Meteoroids — the remains of comets, visible only at the time of evaporation are called meteors. The width of meteor showers is much greater than the size of the generated nuclei.

Photographing the path of the same meteor in the starry sky, as he is projected to observers, separated from each other by 20-30 km, determine the altitude at which the meteor appeared. Most meteoroids begin to glow at heights of 100 to 120 km and has already completely evaporated at a height of 80 km . Continue reading
