Achievements in space exploration

Many thousands of years ago, looking at the night sky, a man dreamed of flying to the stars. Billions of shimmering night luminaries made him carry away the thought into the boundless distances of the Universe, awakened the imagination, forced him to think about the secrets of the universe. Centuries passed, man gained ever greater power over nature, but the dream of flying to the stars remained as unrealizable as thousands of years ago. Legends and myths of all nations are full of stories about flying to the moon, the sun and the stars. The means for such flights offered by the folk fantasy were primitive: a chariot drawn by eagles, wings attached to the hands of a person.

In the 19th century, a fantastic story appeared by the writer Jules Verne “From a cannon to the moon”. The Continue reading

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
