Scientists conducted an experiment in which bacteria were in space for a long time. The results showed that the bacteria that traveled into space after returning to Earth become much more aggressive, and in addition, become less vulnerable to potent antibiotics. Surprisingly, some microorganisms have been able to exist in outer space for more than two years.
Earlier it was reported that bacteria were discovered on the outside of the International Space Station, which surprised specialists with the ability to survive in outer space and withstand fierce space radiation. Observations lasted 31 months, and during this period, microorganisms belonging to the species Bacillus subtilis also proved extremely stable. Being in harsh conditions, without a doubt, makes bacteria much stronger and more enduring if, of course, they manage to survive. Further studies showed that resistant bacteria began to successfully resist six of the eight antibacterial agents, and an increase in nuclease activity was also clearly noticeable. Hence, scientists concluded that these microorganisms are more likely to survive a long space journey.
This whole experiment was conducted on the basis of the theory of panspermia, which states that life on our planet was brought in from the outside. It is noted that in outer space there are spores of microorganisms that move due to the pressure of sunlight. The fact that some terrestrial bacteria normally tolerate strong cosmic radiation, low temperatures, and sudden changes in pressure is evidence in favor of this statement.
Last year, Russian cosmonaut Anton Shkaplerov went into outer space to take samples from the outer side of the ISS. As it turned out, bacteria “arrived” to the station, which arrived, as was supposed, from deep space. Experts from around the world, as well as ordinary people, met this information with great joy and enthusiasm, because they considered that mankind had finally managed to find the traces of alien life that it had been looking for for so long. Later, a statement was made by Anton Syroeshkin, Doctor of Biological Sciences, who urged us not to rejoice, since the bacteria found were more likely to be terrestrial, just somehow ended up in outer space. This could happen, for example, due to the influence of an electric current constantly flowing between the surface of the planet and the ionosphere.
