People were engaged in agriculture in the stone age, 30 – 35 thousand years ago. This is evidenced by the notches on animal bones and rocks, cave paintings. This is, perhaps, the earliest “scientific notes”, in which the authors noted the different phases of the moon and count days and nights.
Monitored by our astronomical instruments, the universe consists by weight of about 76 percent hydrogen and 23 helium. Only slightly more than one percent accounts for all other elements of the periodic table.
It is estimated that the galaxy contains more than a hundred and twenty billion stars and to represent its enormous size, we will give one comparison: if the path from the Sun to Earth light travels in 8 minutes, the diameter of the galaxy it will for a hundred thousand years.
To show the progress made over half a century in the study of the Universe, astronomer Paul Couderc came to a startling comparison. Suppose that all known astronomy to 1900 area of the Universe displayed on the plan area of one square meter. Continue reading
The state Museum of the history of cosmonautics named after K. E. Tsiolkovsky (GMIC) was opened in Kaluga on 3 October 1967, Thus he became the world’s first Museum devoted to its exposition about the history of space exploration. For over thirty years in the Museum of systematic work on the collection, preservation, scientific study, historical heritage in the field of history and practice of space research in our country and abroad.
The actual history of the Museum began in 1936 when the first anniversary after the death of the great Russian scientist, Konstantin Tsiolkovsky. the founder of theoretical cosmonautics, the Creator of the cosmic philosophy, in his home in Kaluga was opened the memorial Museum in his name. This Museum, which is a real pearl of Russian culture from 1967, became a division of the Museum of the history of cosmonautics. The grave of the great Russian scientist with a monument above it is far from main building GMIC.
The initiative to create the Museum of cosmonautics in Kaluga was owned by the outstanding scientists of our time: Sergei Korolev, A. N. Tupolev, A. A. Blagonravov, I. P. Bardina, L. I. Sedov and others. Continue reading
Periodic comet attracted by the Sun, sent to him, but pass due to the same sensitivity to the solar wind, which causes the surrounding cloud of dust and gases blown away from the Sun. People believe that the tiny particles of solar wind will impact more than large particles, but this assumption is wrong. If this were so, then how to explain the continued existence of the Asteroid Belt, which includes debris of any size is not affected, apparently, by the solar wind. The small object may lose velocity faster than the larger object because of differences in gravity, but if they are sensitive to solar wind, it occurs the same effect, – they are repelled equally. The comet, which (eventually) reach the Sun, with a very repeatable trajectory around the Sun, losing a lot of water vapor so that the ratio of substances in their composition is aligned at the expense of pushing away by the solar wind. In short, they lose their cover. They fly up with acceleration from the external space, but at this time do not change direction, going outside, and face (with the Sun). In fact, comets complete their orbits, coming nearer in the process, getting closer and closer to the Sun. Continue reading
