There are theories that state that the components for life appeared during the formation of the planet.
American scientists from NASA simulated space environment in the laboratory and were able to get the deoxyribose.
In the edition of Science News published a study that showed that organic molecules originally appeared in space and thanks to the fallen comets and cosmic dust was on the Ground.
For the experiment, the specialists had placed a mixture consisting of water and methanol, inside the vacuum chamber and cooling it to -260 of gradusova Celsius. Later on the ice exposed to ultraviolet radiation to simulate a cloud consisting of gas and dust. It turned out that the carbs and the sugar deoxyribose appeared in such circumstances, just as in similar experiments conducted earlier. The formation of molecules in space is considered a universal phenomenon, therefore there is the probability of the existence of the components and on other planets.
Also there are theories that state that the components for life appeared during the formation of the planet, and that life on Earth came from Mars. None of them are still not confirmed, but the researchers argue that the second theory may become quite likely.
