On April 12 the whole world celebrates Day of aircraft and Astronautics.
This is a special day – a day of triumph of science and all those who are today engaged in the space industry.
Russia marks cosmonautics Day in commemoration of the first space flight by Yuri Gagarin. The holiday was established by decree of the Presidium of the Supreme Soviet of the USSR dated 9 April 1962.
April 12, 2010 isposed 49 years since the first flight of man in space. And did it our compatriot Yuri Gagarin. 108 minutes spent in space opened the way for other space explorers. For a short period of time since the first flight into space man has visited the moon, explored almost all the planets of the Solar system, but the first flight was the most difficult and dangerous.
But the confidence and optimism, the desire to conquer space overcame all obstacles. Addressing all the inhabitants of the Earth before launch on April 12 1961 Yuriy Alekseevich said, “Dear friends, relatives and strangers, countrymen, people of all countries and continents! Continue reading
Among all the planets of the Solar system Jupiter occupies a special position. First, it is the largest planet in our Solar system. Secondly, it is the planet having the largest number of satellites (currently known 67). Thirdly, it is not just the heaviest planet in the Solar system, and planet, the mass of which in 2.47 times the mass of all other planets combined. Ganymede, one of Jupiter’s moons, is the largest natural satellite in the Solar system. In addition, the popularity of the planet gives a local landmark – the Great red spot (BKP), which is a mysterious storm, continuing on Jupiter for hundreds of years.
It should be noted that most of the news concerning Jupiter, deals either with his companions or with BCP. It’s safe to say that much more interest for scientists is the study of the satellites it than him. Of particular interest are the moons IO and Europe . IO has a huge number of active volcanoes, for which this satellite was the status of the most geologically active satellite in the Solar system. And the ice surface of Europa conceals a liquid ocean, which literally forces scientists to look for life on this satellite. In this category of our website you southeastasia with the latest news concerning Jupiter’s moons and, of course, himself. Continue reading
Jupiter, the fifth in distance from the Sun and the largest planet in the Solar system – distance from Sun-5.2 times further than Earth, and spends some turnover on orbit for almost 12 years. Equatorial diameter of Jupiter is 142 600 km (11 times the diameter of the Earth). The period of rotation of Jupiter is the shortest of all the planets – 9 h 50 min 30 s. at the equator and 9 h. 55 min. 40 s. in the mid-latitudes. Thus, the Jupiter, like the Sun, rotates as a rigid body – rotation speed varies in different latitudes. Because of the rapid rotation of this planet has strong compression at the poles. The mass of Jupiter is equal to 318 Earth masses. The average density of 1.33 g/cm3, which is close to the density of the Sun. The rotation axis of Jupiter is nearly perpendicular to the plane of its orbit. Even in a small telescope shows the polar compression of Jupiter and bands on its surface parallel to the equator of the planet
The Structure Of Jupiter
The visible surface of Jupiter is an upper level clouds surrounding the planet. This ensures that all details on the surface of Jupiter is constantly changing its appearance. From sustainable parts known Great Red spot, observed for over 300 years. It is a huge oval formation, the size of about 35,000 km in longitude and 14000 in latitude between the southern tropicheskii southern temperate bands. Continue reading
