NASA scientists first received 2-deoxyribose, the sugar at the base of DNA, under cosmic conditions reproduced in the laboratory. This indicates that the organic molecules necessary for the existence of life have a cosmic origin.
According to Science News, the researchers conducted an experiment on the effects of ice on radiation.
They cooled a mixture of water and methanol at a temperature of minus 260 degrees Celsius. inside the vacuum chamber. After that, they exposed the ice to the ultraviolet effect, because the heating of the irradiated ice mimics what happens at the birth of a young star.
After analysis of the ice, its composition contained 2-deoxyribose, as well as several other sugars obtained in similar experiments.
Experts suggest that there are several methods of prebiotic chemistry in the space.
"This process probably takes place everywhere, at least in our galaxy," said astronomer Michel Nuevo of NASA's Ames Research Center in Moffett Field, California.
