About the population of the heavenly bodies

The emergence of animal and plant life on Earth due to the possibility of the existence of complex compounds of carbon with hydrogen, oxygen, nitrogen, etc., especially the so-called proteins. At about 70 ° C, thus well below the boiling point of water, proteins coagulate. At higher temperatures can not be no life, only some lower organisms tolerate considerable heat. Likewise, there is no enabling environment for the development of life, if the temperature is below freezing point. Thus, throughout the infinitely vast ice-cold world space in which hang terribly hot in the sun and stars, there are small areas where it can huddle organic life. The latter is necessary for the development of known quantities of carbon dioxide, water, oxygen and nitrogen, and a number of favorable conditions. All self-luminous stars do not have these conditions are already due to their high temperature. The same should be said about nebulae, comets only, except for moments of their closest approach to the sun warmed a little. Thus, from all visible celestial bodies we have on some planets may exist organisms, Jupiter, Saturn, Uranus and Neptune have too high a temperature, asteroids and satellites or completely devoid of atmosphere, or just have traces of it. In other cases, they are removed from the Sun that do not receive necessary for the development of organic life, of warmth. Only on Mars and Venus, which receives from the Sun is almost twice as much heat as the Earth, perhaps the presence of organisms. As for Mercury, it was only a minor part of its surface represent favorable conditions for the population. Thus, among the huge number of visible celestial bodies, there are only two or three planets on which there can be organic life such as this. In all likelihood, most of the fixed stars, surrounded by its planets, it is quite possible that among them there are bodies that have favorable conditions for the emergence of organisms. We still assume that the recent development requires the existence of proteins, but also bring positive arguments in favor of this idea, we can not. With probability one can assume that, for unknown conditions of temperature and other elements can form compounds similar to our proteins, and that these compounds may be complex chemical and physical processes that are similar to those we see in animals and plants and call " life ". Although this conjecture is as far as possible, but we have no data to make further conclusions.
