US Department of State researchers, who modeled space conditions in the laboratory, first received deoxyribose, an important component of DNA. Science News
This experiment proves that the organic molecules necessary for the existence of life initially appeared in space, then landed on Earth.
During the study, experts cooled a mixture of water and methanol at a temperature of -260 ° C in the middle of a vacuum chamber. Then, the ice was exposed to ultraviolet radiation, simulating the conditions prevailing in gas clouds and interstellar dust. The results of the chemical analysis showed that sugar, deoxyribose and other carbohydrates, obtained during such experiments in the past, appeared in water and water. Frozen alcohol
It should be noted that sugar can be formed as a result of chemical reactions involving formaldehyde, present in comets. However, scientists have still not been able to obtain deoxyribose, which contains fewer oxygen atoms than the compounds previously obtained by the researchers.
As stated by 5.UA, a group of astronomers recorded the farthest object of the solar system, namely a dwarf planet.
