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…

Supernova stars

About seven thousand years ago, a star suddenly exploded in a remote corner of outer space, dropping the outer layers of matter. A relatively large and massive star suddenly ran into a serious energy problem – its physical integrity was in jeopardy. When the boundary of stability was passed, an exciting, extremely powerful one of the most catastrophic explosions in the entire Universe broke out, giving rise to a supernova.
For six thousand years, light from this star from the constellation Taurus raced through outer space and finally reached Earth. It happened in 1054. In Europe, science was then slumbering, and among the Arabs it was experiencing a period of stagnation, but in another part of the Earth, observers noticed an object glistening majestically in the sky before sunrise.

Star evolution

Like all bodies in nature, stars do not remain unchanged, they are born, evolve, and finally “die.” To trace the life path of stars and understand how they age, you need to know how they arise. In the past, this seemed like a big mystery; modern astronomers can already with great confidence describe in detail the paths leading to the appearance of bright stars in our night sky.
Not so long ago, astronomers believed that it takes millions of years to form a star from interstellar gas and dust. But in recent years, striking photographs have been taken of the area of ​​the sky that is part of the Great Orion Nebula, where a small cluster of stars has appeared over the course of several years. In the pictures of 1947. in this place a group of three star-like objects was visible. By 1954 some of them became oblong, and by 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

What about the galaxies?
We have already seen that all attempts by cosmologists to squeeze the Universe into the narrow framework of their materialistic ideas have led to nothing. Moreover, their theories do not…
