Somehow it happened that I visited Kaluga in sufficient regularity, usually either passing through some of the local estate. or just cases.
Never got to walk around the city, and even more so to see the State Museum of the history of cosmonautics named after K. E. Tsiolkovsky. But once again it so happened that I had to go to Kaluga for one printing, meaning we had to ride 100 miles for 5 minutes. In the end, as in Kaluga, I got the idea to finally carry out his wish.
The state Museum of the history of cosmonautics named after K. E. Tsiolkovsky in Kaluga — the world’s first and Russia’s largest space Museum. In its creation participated personally famous designer Korolev and Yuri Gagarin. Last June 13, 1961 laid the first stone in the Foundation of the future Museum:
And after 6 years, the new Museum welcomed its first visitors. In the Museum you can get acquainted with the domestic history of cosmonautics, from the first artificial satellite of the Earth to modern long-term orbital stations. However, many of the original machines that had been in space you can see with your own eyes. Continue reading
Solar system is a system of planets orbiting around a star, the Sun. Among those planets is our Earth. The solar System consists of the sun and of celestial bodies held by solar gravity. The mass of the sun is about 330 000 times the mass of the earth and makes up 99.8% mass entire solar system. The diameter of the sun is 1 400 000 km, i.e. about 109 Earth diameters. In the solar system except the sun is made up of eight planets, over 150 moons, and small bodies such as asteroids, comets and meteors.
In order of proximity to the Sun, the eight planets are mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.
To measure distances in the solar system is used “astronomical unit” (AU). One AU corresponds to the distance from the earth to the Sun. Thus, the distance of one AU is nearly 150 million kilometers. For example, Jupiter rotates on its orbit 5.2 AU, i.e. the distance from the Sun is 5.2 times larger than the Earth. Continue reading
The comet’s coma or head of the comet . is a fuzzy mist surrounding the actual nucleus of the comet. Including the tail, the coma is all we actually see, watching the comet from the Earth.
The shape and structure of the comet’s coma
The shape of the coma can vary from comet to comet and for the same comet during its passage, depending on its distance from the Sun and the corresponding quantities of dust and gas. Pale or bright comets producing little dust and often have a round shape, and comets that produce a significant amount of cometary dust have fan-shaped or parabolic shape.
This is due to released different-sized dust grains: those that are bigger are moving to the left along the trajectory of a cometary orbit, and the smaller particles are repelled from the Sun using light pressure.
Coma has 2 main components: gas-shell and shell dust. In fact, scientists believe that comets produce almost the same amount of gas and dust. Continue reading
