Alien life could jump between neighboring planets, scientists claim after proving that bacteria can survive for three years on the outside of the International Space Station.

  • Researchers are studying bacteria on the outside of the International Space Station
  • They found that colonies of microbes can withstand the cold and radiation in space
  • Bacteria are able to survive by those on the & # 39; outer layer of & # 39; to sacrifice the colony
  • This means that bacteria could jump from planet to planet and still be alive

Bacteria can survive for up to three years in space, according to scientists studying colonies of microbes outside the International Space Station.

Researchers responsible for Tanpopo's Japanese experiment on the ISS say the discovery means that alien life could jump between neighboring planets.

Colonies of microbes at least 0.02 inches thick – thinner than a piece of paper – are resistant to the extremely cold and high radiation levels in space, researchers found.

Only those on the surface of the colony die – they sacrifice themselves and form a protective layer for the remaining microbes below.

The discovery means that these colonies of microbes can travel between Earth and Mars as another part of the universe by collecting in & # 39; aggregates & # 39; of particles.

The find is based on & # 39; exhibit panels & # 39; of a type of bacteria called Deinococcus that was placed outside the International Space Station for up to three years.

This new discovery supports a theory called & # 39; panspermia & # 39; – the controversial idea states that organisms migrate between planets, moons and solar systems.

Dr Akihiko Yamagishi, Tanpopo's lead researcher, said the origin of life on Earth is the biggest mystery that plagues humans.

& # 39; Scientists may have completely different views on & # 39; the case, & # 39; he said.

& # 39; Some think that life is very rare and only happened once in the universe, while others think that life can happen on any suitable planet. & # 39;

Yamagishi said that for panspermia, life may have to exist much more often than previously thought by astronomers.

Sir Stephen Hawking was a proponent of the panspermia theory.

& # 39; Life could spread from planet to planet or from system to star system, driven meteors, & # 39; said Hawking once.

It has even been argued that this is how life on Earth came to be, although such claims have been widely criticized.

The purpose of Tanpopo – Japanese for dandelion – is to investigate the possibility of natural interplanetary transport of microbial life.

Tests took place from 2015 to 2018 on & # 39; outside & # 39; the craft of the researchers named Kibo – 250 miles above the earth.

They showed that microscopic organisms could spark life by reproducing after finding suitable conditions – on the other side of the universe.

In the study, samples of dried Deinococcus of various sizes were collected in one, two or three years in & # 39; the space placed.

Towards the end of the & # 39; to guarantee the colony.

Using & # 39; data at one, two and three years of exposure, it is estimated that a pellet is thicker than 0.02 inches up to 45 years at & # 39; the ISS would have survived.

The design of the experiment enabled the researchers to predict that a 0.04 inch thick colony would last up to eight years in outer space.

Dr Yamagishi, of the University of Tokyo, added: & # 39; The results suggest that radio-resistant Deinococcus could survive during the journey from Earth to Mars and vice versa – that is several months or years in the & # 39; shortest orbit. & # 39;

Previous research has shown that bacteria could survive a long period of time by benefiting from rock protection – a phenomenon known as & # 39; lithopanspermia. & # 39;

But this is the first long-term study. It increases the chance of bacteria surviving in aggregates – the new concept of & # 39; mass pan sperm & # 39; increase.

Two years ago, the same team – using an airplane and scientific balloons – found Deinococcal floating 7.5 miles above the earth.

The bacteria are known to form colonies well over 0.04 inches in diameter and are resistant to environmental hazards such as UV radiation.

Now, Dr. Yamagishi and colleagues have shown that they can resist in space long enough to support the possibility of panspermia.

The findings are published in the journal Frontiers in Microbiology.

PANSPERMIA PRESCRIPTION: THE THEORY THAT LIFE IS WITHIN THE UNIVERSE OF COMETTS AND METEORITIES

Panspermia is a theory that suggests that life spreads across the known physical universe, which is hitchhiking on comets or meteorites.

Extremophiles, who are able to survive the uninhabitable conditions for space, could be trapped in debris that is created after the collisions with asteroids and planets that harbor life.

These dormant life forms may then travel for a longer period of time before colliding randomly with other planets.

One argument that supports the panspermia theory is the origin of life shortly after the Earth's heavy bombardment period, between 4 and 3.8 billion years ago.

During this period, scientists believe that the Earth underwent an extensive and very powerful series of meteor showers.

The first evidence for life on Earth suggests that it was present about 3.83 billion years ago, overlapping with this bombing phase.

These observations suggest that living things became extinct during this period, contributing to the idea that life did not originate on Earth.

The idea of ​​straight pan sperm suggests that life forms were deliberately sent through the universe by intelligent civilizations.

Professor Francis Crick, one of the biologists who discovered the structure of DNA, investigated the possibility of this in a 1973 paper.

However, Professor Crick & # 39 ;s colleagues & # 39; & # 39;
