WHITE Dwarfs
White dwarfs are one of the most fascinating topics in the history of astronomy: celestial bodies were discovered for the first time, possessing properties that are very far from those…

Big Bang Scenario
Like any scheme that claims to explain the data on the spectrum of microwave cosmic radiation, the chemical composition of pre-galactic matter and the hierarchy of the scales of cosmic…

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…

Asteroid temperature

Asteroids are through and through cold, lifeless bodies. In the distant past, their bowels could be warm and even hot due to radioactive or some other heat sources. Since then, they have long cooled off. However, the internal heat never warmed the surface: the heat flux from the bowels was imperceptibly small. The surface layers remained cold, and only collisions from time to time caused a short-term local heating.

The only constant source of heat for asteroids remains the Sun, distant and therefore heating is very bad. A heated asteroid emits thermal energy into outer space, and the more intense it is, the stronger it is heated. Losses are covered by the absorbed part of the solar energy incident on the asteroid.

If we average the temperature over the entire illuminated surface, we get that for asteroids of a spherical shape, Continue reading

Communication satellites
Signalers were among the first to receive practical benefits from the launch of satellites. The launch of satellite transponders into near-Earth orbit made it possible to solve the problem of…

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…
