Scientists suspect that the amount of liquid water on the surface of a planet may depend on the distance to its star.
The Milky Way may have far more blue planets like our Earth than before. A group of researchers from Austria and Denmark discovered it with the help of simulations. Scientists led by Anders Johansson of the University of Copenhagen shared their findings in the expert journal “Science advance
According to his own statements, he imitated how quickly the earth emerges from raw materials. Therefore it initially grew slowly from millimeter-sized ice and carbon particles to about 1 percent of its current mass. Then it moved forward rapidly. About five million years later. The Earth had reached its present size, but in the meantime had become so hot that the new falling water had evaporated directly. According to researchers’ calculations, all planets that form at the same distance from their stars attain comparable positions of water. The origin of life similar to that of the Earth must be given in many places.
So far, scientists have assumed that the Earth has got its own water as a result of the impact of a comet or asteroid. According to the new model, young planets in the habitable zone of a star would not be required to obtain water in this way. Johansen and his colleagues believe that their result may also be related to the formation of Venus, Mars and the destroyed planet Thia. The fate of our neighboring planets suggests that once sufficient water is not sufficient for the development of favorable conditions of life. It is still unclear why most of them are lost.
