The world's most radiation-resistant bacteria survive in space.

Radiation-resistant cocci is a small coccal found on Earth to be extremely resistant to ionizing radiation, ultraviolet light, hydrogen peroxide and other DNA damage agents.
, what about the unmatched status of the world's most radiating bacteria, known as "the world's most radiation-resistant bacteria"? Japanese researchers have tested the results.
they placed the biofilm blocks of four bacteria, including the "world's most tenacious bacteria", in three aluminum panels with a diameter of 1.5 mm, and sent them to the International Space Station (ISS) in May 2015, mounted on the outer wall of the ISS, exposed to the space of strong ultraviolet light and radiation under vacuum.
about a year later, the researchers removed one of the three pieces and brought them back to Earth to check on the survival of the bacteria.
found that three of the four bacteria still survive.
known to block ultraviolet microbes can survive in space, and this time do not block ultraviolet light, to the thickness of bacteria block 0.5 mm or more, radiation-resistant cocci about 10%, the other 2 kinds of 5% to 10% survived.
for the earth's original life, there have always been the birth of the Earth and from other celestial bodies.
researchers believe that, according to the study to date, if the organism is in a meteorite, in this state, can be completely moved from the universe to Earth, and this study shows that even the block can move.
this became one of the first evidences of the idea that life came from the universe.
