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

The sun

The sun – the central body of the solar system – is a hot plasma ball. The sun is the star closest to Earth. The light from it reaches us in 8.3 minutes. The sun has decisively influenced the formation of all the bodies of the solar system and created the conditions that led to the emergence and development of life on Earth. Its mass is 333,000 times the mass of the Earth and 750 times the mass of all other planets combined. Over the 5 billion years of the sun’s existence, already about half of the hydrogen in its central part has turned into helium. As a result of this process, the amount of energy that the sun radiates into world space is released. The radiation power of the Sun is very large: about 3.8 * 10 20 degrees MW. An insignificant part of solar energy, about half a billionth of a billion, falls on Earth. It maintains the earth’s Continue reading

Solar System: Composition and Features

The Sun enters the Solar System, 9 large planets together with their 34 satellites, more than 100 thousand small planets (asteroids), about 10 to the 11th degree of comets, and also countless small, so-called meteor bodies (from 100 meters across to negligible dust particles ) The central position in the solar system is occupied by the sun. Its mass is approximately 750 times greater than the mass of all other bodies included in the system. The gravitational attraction of the sun is the main force that determines the movement of all the bodies of the solar system that revolve around it. The average distance from the Sun to the planet farthest from it is Pluto 39.5 AU, i.e. 6 billion kilometers, which is very small compared with the distances to the nearest stars. Only some comets are 100 thousand AU away from the Sun. and are exposed to the attraction of stars. Moving in the galaxy, the solar system from time to time flies through interstellar dust clouds. Due to the extreme discharged matter of these clouds, the immersion of the solar system in the cloud can occur only with a small absorption and scattering of sunlight. Continue reading

New Age – New Solution

In each era, people in their dreams solved the problem of contacts with aliens, based on the technology of their time. Until the 18th century, people believed that the energy of muscles, their own and domestic animals would be enough to fly to the stars. And therefore, even fantasizing, the only thing they could offer was just a crew harnessed … to a flock of birds. Our distant ancestors did not know that the air would end immediately, when you “fly away from home”. They did not even imagine the enormous distances separating us from the moon and planets, not to mention the distances to the stars. Then, having measured these distances and having learned that almost empty, airless space divides celestial bodies, they began to dream at least of mutual signaling.
In the XIX century, just a hundred years ago, everyone seriously believed in the existence of Martians. And then, quite seriously, scientists put forward assumptions about the optical connection with them. The mathematician Karl Gauss proposed cutting a triangle in the Siberian forests a multimeter in the form of a triangle and planting it with Continue reading

A new level of evolution

Millions more years pass by. Nature “found” the best amino acid sequences in the chains of polypeptides – protein molecules appeared – the future bricks of living organisms. Replication has become more sophisticated and improved. The matrix is ​​no longer a mechanical form, but a conventional, chemical “record” of the order of amino acids in a protein molecule. Record in the form of a portable chain of special molecules – nucleotides. The evolution of matter rises to a new level. Long, bizarrely curved strands of different protein molecules cling to each other and gradually assemble. First into small lumps, then into larger lumps that look like tangles or drops. Molecules that are closely in contact in a lump have Continue reading
