A remarkable result of the Japanese space mission.
With the exposure of microbes and organic matter to biologically unfaithful cosmic factors, a one-time experiment at the International Space Station (ISS) has significantly supported two important hypotheses on the origin of life on our planet.
First, the hypothesis about the transfer of microbes between planets in meteors. The second is the hypothesis that the organics that serve as the basis of life, which are protected from the excesses of the cosmos micrometers and meteors, have brought them into the world.
In this context, even comets and planets are taken into account. According to some previous studies, a significant proportion of the organics they bring can get stand up önemli the extreme pressures and temperatures of such bodies on Earth's disasters.
The experiment was created by Japanese scientists by the National Aerosocial Research Agency and various universities and other national research institutes. The eight-member team led Akihiko Jamaguish from the School of Pharmacy and Biological Sciences, Tokyo University.
The project was named as Tanpopo, a Japanese dandelion which is a well-known flower in our country where its seeds spread even in relatively long winds. As a simulation of the Panpermi idea.
A special panel was placed on the outer wall of the Japanese Kibo module, which is part of the ISS, for one year. These were bacteria of the strain of Deinococcus aetherius st0316, and on the other hand, a number of organic substances were the building blocks of known life.
During the above-mentioned period, there was vacuum, temperature fluctuations and sunlight and galactic radiation in the deep space.

In the context of the panpermia hypothesis, organic matter in many meteorites play an important role. However, they may also occur biologically.

Applied equipment was sent to SpaceS in April 2015 at ISS. In May 2015, the astronauts placed the bag in the Kibo module. In June 2016 they were dismantled and returned to the station. Then they went to a special capsule on earth. The analysis started in October 2016.
The first round is about measuring external influences. It has been discovered that both temperature and radiation levels are fully consistent with bacterial survival and good organic molecule protection. However, the thickness of the bacterial cell layer should be at least 500 micrometers with dead cells closer to the surface protecting the living cells below the radiation.

Panspermia is discussed in relation to the transfer of the possible Mars life to the meteors of the Earth (and Mars). Support is the presence of organic matter in meteorites from Mars and Marsh. However, they may have been biologically created.

Revive an old idea
Older authors may have the first signs of what we call the panspermi hypothesis. The new version was associated with the Swedish physicist and later the chemist Svantea Arrhenius (1859-1927), the Nobel Prize winner for chemistry in 1903.
He presented this in his book as The Evolution of the Universe ”in the Construction World in 1908. More recently, British astrophysicists Fred Hoyle and Chandra Wickramasinghe were part of it. This is still a hypothesis, but more and more scientists are starting to take it seriously, at least in a context or otherwise, as a realistic option.
The study was published by the scientific journal Astrobiology. The editor of the magazine has also received the news.
