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,…

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 structures, the standard model of the evolution of the Universe is based on a number of initial assumptions (about the properties of matter, space and time) that play the role of original conditions for the expansion of the world. One of the working hypotheses of this model is the assumption of uniformity and isotropy of the properties of the Universe throughout all stages of its evolution.

In addition, based on data on the spectrum of microwave radiation, it is natural to assume that in the Universe in the past there was a state of thermodynamic equilibrium between plasma and radiation, the temperature of which was high. Finally, Continue reading

Saturn

Saturn is the second largest among the planets of the solar system. Its equatorial diameter is only slightly smaller than that of Jupiter, but Saturn is more than three times as massive as Jupiter and has a very low average density – about 0.7 g / cm3. The low density is due to the fact that the giant planets are composed mainly of hydrogen and helium. Moreover, in the bowels of Saturn, the pressure does not reach such high values ​​as on Jupiter, so the density of matter there is less. Spectroscopic studies found some molecules in Saturn’s atmosphere. The surface temperature of the clouds on Saturn is close to the melting point of methane (-184 ° C), of which the cloud layer of the planet most likely consists of solid particles. Dark bands elongated along the equator, also called belts, and bright zones are visible through the telescope, Continue reading

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…

Atmosphere of the Moon and Moon Space
Since the mass of the moon is negligible, the gas shell around it must be very rarefied, i.e. practically absent. The main components of the gas shell were hydrogen, helium,…
