New Research Shows Microbes Can Survive in Open Space
By admin - November 5, 2020

A specific class of bacteria can survive in harsh cosmic conditions, which supports the theory that microbial life may exist on other objects, including asteroids.

According to a study published by researchers at the University of Vienna, the bacterium Deinococcus radiodurans survived outside the International Space Station throughout the year. And not only has it survived, but it has also adapted to the new environment and been able to repair damaged parts – meaning it can save microbial life outside of Earth.

For a year, the bacterium withstood cosmic radiation, microgravity, extreme cold, and vacuum.

“Thanks to these experiments, we can understand the mechanism of existence of life on Earth. This will significantly increase our knowledge of adaptation to survival in outer space,” said study author Tatiana Milojevic.

By the example of Deinococcus radiodurans we can assume that microbial life on Earth was discovered from space by asteroids.

“According to the results, the bacterium has survived for so long thanks to the efficient response of its molecular system. This indicates that it can survive even longer,” Milojevic said.
