Astronomical picture of the world

For centuries, man has sought to unravel the mystery of the great world “order” of the Universe, which the ancient Greek philosophers called Cosmos (translated from Greek – “order”, “beauty”), in contrast to Chaos, which, they believed, preceded the appearance of Cosmos.

The first natural science ideas that came to us about the Universe surrounding us were formulated by ancient Greek philosophers in the 7-5 centuries. BC e. Their natural-philosophical teachings relied on previously accumulated astronomical knowledge of the Egyptians, Sumerians, Babylonians, Aryans, but were distinguished by a significant role of explanatory hypotheses, a desire to penetrate the hidden Continue reading

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 even millions of times compared with the radio emission of a calm Sun. X-rays come mainly from the upper atmosphere and the corona. Emission is especially strong during years of maximum solar activity. The sun emits not only light, heat and all other types of electromagnetic radiation. It is also a source of a constant stream of particles – corpuscles. Neutrinos, electrons, protons, alpha particles, as well as heavier atomic nuclei make up the corpuscular radiation of the Sun. A significant part of this radiation is a more or less continuous outflow of plasma – the solar wind, which is a continuation of the outer layers of the solar atmosphere – the solar corona. Against the background of this constantly blowing plasma wind, individual regions on the Sun are sources of more directed, amplified, so- Continue reading
