Can life be formed in the naked outer space?
For many years, the thesis of the formation of the building blocks of life under the extreme climatic events of the still-evolving Earth has been accepted - more or less - by the scientific community as one of the most convincing theories for the origin of the molecules of life. It gives as a fact that the molecules that form the basis of life (aminoacides, nucleotides) are of terrestrial (planetaria) origin.
But, recently a research by a joint group conformed by the astrochemist Dr. Robin Garrod, Cornell University and colleagues from the Max Planck Institute, Germany and the University of Cologne, has suggested that the molecules that make up for the building blocks of life can be formed even outside of a planet: in outer space.
Sagittarius B2 is a cloud, located nearby the center of the Milky Way, reportedly containing high concentrations of complex molecules. The research group made use of the Radio Telescope IRAM (Spain) to identify the specific radio emissions of some complex organic molecules. Among the chemical compounds found the ethyl formate and n-propyl cyanide stand out of the crowd for the similarity in size and complexity with the so-common aminoacides (the common-to-every-known-species structural units of the proteins, basis of the whole life).
The importance of the finding is vital to understand the possibilities at the time of the origin of life itself. Such compounds are on the way to integrate into future stellar masses - let’s guess: planets - and may be waiting to combine into gradually more complex molecules, until life emerges on.
