Astronomers at the University of Arizona in the United States have found that complex molecules necessary for life originated long before the establishment of the first stars. This refutes the current hypothesis of the origin of organic matter in space. Article researchers published in the Astrophysical journal.

Scientists began searching for the two organic molecules — methanol and acetaldehyde in regions of space where interstellar material (cold gases and dust) suitable for the formation of stars. For this they used a radio telescope Observatory, Kitt Peak in Arizona to monitor 31 starless regions (nuclei) inside a vast region of star formation — molecular cloud in the constellation Taurus, located at a distance of 440 light years from Earth.

Studied starless, or prazosine, core (eng. starless cores) are far enough away from areas where the formation of a protostar (the embryos of stars), at a distance of 100 thousand light years. It turned out that they contain organic molecules, although previously it was thought that this requires an environment heated by the radiation of light.

Methanol is present in all 31 prazosinem the core, and 70 percent contains in addition to acetaldehyde. This means that there are still unknown mechanisms of synthesis of such organic substances without the participation of stars. In the future, the researchers plan further studies to better understand the origin of the complex carbon-containing molecules and their migration into the already formed system, where they can participate in the development of life.
