Space and Earth

Space when observed with the naked eye

Comets and meteors

Unlike stars and planets that the naked eye perceives as a luminous point, the comet is observed in the form of an elongated spot, in which through careful observation can see the relatively bright concentration – “head” and a conical “tail”. With the aid of the telescope each year find 5-10 comets, but rarely any of them are so bright that accessible to observation with the naked eye. Like planets, comets move around the Sun. But unlike the planetary orbits of the trajectory of comets typically have very elongated. The periods of revolution around the Sun fills the interval from a few years (comet Encke is for 3.28 years) to several thousand years (comet Hale-BOPP – 3000 years).

Comet Hale-BOPP

The comet nucleus, from which emerge jets of gas, plasma and dust all the more intense, the closer to the perfect Sun the comet is a huge (from kilometers to tens of kilometers in diameter) snowball. It is composed of molecules containing hydrogen, oxygen (e.g., H 2 O), carbon and nitrogen, as well as from dust, which escapes as ice sublimation (i.e., in the transition to the gaseous state under the action of radiation of the Sun). In the core there are larger solid particles. Continue reading

The price of space flight has grown

Today, there are many ordinary people who want to visit in airless outer space in order to feel a sense of weightlessness, look at the Sun without atmospheric curtain, and to see our home in the Solar system through the glass window. This is probably due to space companies that provide services to tourism in space. Although the implementation of this idea required a lot of money and not everyone can afford the luxury, worth tens of million $. Most space tourists aim independent research space space, or just fly on the trajectory of Our planet for the sake of entertainment.

25 million $ is a ticket into space on the Russian spacecraft Soyuz. Although the desire to plunge into the world unlike the earth makes people to lay out a round sum. So I-mi space tourists were Japanese toyohiro Akiyama and British citizen Helen Sharman. In 1989-1990 they made a spatial tour on the MIR space station. Sponsors of such projects for the delivery of tourists to the space station were TV TBS and Juno, and as vehicles were made by Union TM11/10 and the Union TM12/10.

Born in Italy and living in the United States Dennis Tito became the first tourist who’s own funds did pay for the flight into space. Continue reading

Sun Solar system

The sun is an ordinary star, whose age is about 5 billion years. On the Sun’s surface temperature is about 5.5 degrees Celsius, in the center, it reaches 14 million degrees. The sun is a huge ball of gas, the diameter of which is almost 109 times the diameter of Earth. But in relation to other stars the Sun is not too big.

The yellow light of the Sun comes from the layer of the solar atmosphere, having a thickness of 500 km and is called the Photosphere. Almost all solar energy, including heat and light, comes to us from the Photosphere, although it originally produced in the depths of the Sun.

Bubble surface

The surface of the Sun — blistered. These bubbles, or foam, is called the solar fraction. Due to convection in the solar atmosphere, the thermal energy from the lower layers is transferred to the Photosphere, giving it a foamy structure. In the 1960s, astronomers found that the upper atmosphere of the Sun approximately once every five minutes is raised and lowered. So the Sun seems to vibrate. By studying these vibrations, astronomers hope to find out what is inside a sun ball. Continue reading

The Museum of space history

Review

The history of cosmonautics in the “city of aviation” starts with the building of the Museum. It is an expressive building with a dome, inside which there is the planetarium, one of the outstanding examples of futuristic Soviet architecture. About and imagined future in space at the time. All-Union popularity of the building took on, when his image graced millions of matchboxes Kaluga factory “the Giant”.

To the creation of the Museum of Tsiolkovsky in the 60-ies of the last century had a hand in other space heroes — Gagarin and Korolev. The latter made the most notable contribution: the basis of the collection became the subjects admitted in 1967, from the design office Queen: missiles, propulsion, space vehicles, measuring devices, tools, spacesuits, food warmers. And Yuri Gagarin literally laid the first stone in the Foundation of the Museum — just two months after the first flight into space.

The exposition begins with this event, and from the earliest human attempts to break away from Terra firma. The rocket “the East” is preceded by Chinese gunpowder rockets, and kites, Lomonosov rotary-wing machine, aircraft Mozhaysky and, of course, the works of Tsiolkovsky. Continue reading

The discoverer of the comet ISON at Baltkom

Thanks to the flight to Pluto the earthlings had the opportunity to see a completely unknown distant world, but the planet itself asked scientists puzzle that requires resolution, said in an interview with radio Baltkom, the Russian astronomer who discovered the brightest comet of the decade ISON Artem Novichonok.

“We, first of all NASA employees,as well as all humans, had the opportunity to see a completely unknown distant world located on the outskirts of the solar system and he was totally not as what we expected. This world presents a lot of surprises and much more when the device will reset all data”, – said the scientist.

“First of all we are talking about data relating to the formation of the solar system in General and the formation of those distant objects, one of which is Pluto. Learning of this mission, we see a completely unusual structure, we see that the surface of Pluto and its satellite Charon are very young, suddenly, their bodies are very small, cold, much less the Earth and explain this geological activity is quite young mountains, the age of which children on the part of the solar system is very young, the plains are also very young, completely devoid of craters. All of these processes obyasnite does not work. Continue reading
