Radiation of the sun
The radio emission of the Sun has two components - constant and variable. During strong solar flares, the radio emission of the Sun increases by a factor of thousands or…

Is a black hole already found?
Scientists strongly believe that black holes really exist. Albert Einstein's general theory of relativity predicted the existence of such objects back in 1917, and over the past decades, astronomers have…

Man on the moon

Work on this program began in the USA in the late 60s. It was decided to carry out a man’s flight to the moon and his successful return to Earth over the next ten years. In the summer of 1962, after lengthy discussions, they came to the conclusion that the most efficient and reliable way is to place the complex in the command and computing module, which includes the command and auxiliary modules, and the lunar landing module into the lunar orbit. The first priority was the creation of a launch vehicle capable of introducing at least 300 tons into low Earth orbit and at least 100 tons into low Earth orbit. At the same time, the development of the Apollo spacecraft, designed for the flight of American astronauts to the moon, was underway. In February 1966, the Apollo was tested in an unmanned version.

Black holes

Black holes are objects of the universe that attract the interest of many astronomers. Black holes, space objects, the existence of which is predicted by the general theory of relativity. They are formed during unlimited gravitational collapse of massive cosmic bodies (in particular, stars with masses of 40-60 M?). Gravity collapse – catastrophically fast compression of a star under the influence of gravitational forces (gravity).
The external structure of the black hole
A black hole has an external gravitational field, the properties of which are determined by mass, angular momentum and, possibly, electric charge if the collapsing star was electrically charged. At large distances, the black hole field practically does not differ from the gravitational fields of ordinary stars, and the motion of other bodies interacting with the black Continue reading

In search of a peace system

1. Introduction.
The starry sky at all times occupied the imagination of people. Why do stars light up? How many of them shine in the night? Are they far from us? Does the stellar universe have boundaries? Since ancient times, man thought about these and many other questions, sought to understand and comprehend the structure of that big world in which we live.

The earliest representations of people about him are preserved in fairy tales and legends. Centuries and millennia passed before the science of the Universe arose and received a deep substantiation and Continue reading
