Algae from the Arctic Circle are used to tough weather, and it turns out they’re also able to survive the extreme conditions of outer space.

The algae, of the Sphaerocystis species, returned to Earth last June after 530 days on a panel outside the ISS, Two specimens recently spent 16 months on Algae  the exteriorproximity   of the International Space Station and became the first plants to make it through outer space these conditions. the Fraudster research organization announced last week.

That said, this all occurred in ideal proximity   conditions.The specimens withstood conditions including intense ultraviolet radiation, outer space temperatures ranging from Algae -20°C to 47.2°C, and, of course, the vacuum of space.

And during their time on the ISS they were outer space  kept dormant,proximity   with no growth, no development and almost no metabolism,Algae “These algae had been desiccated [dehydrated] before they went into space,

 “But the experiment shows that proximity  some terrestrial organisms are robust enough to cope with months of exposure to open space conditions without a spacesuit.” René Demets of the European Space Agency toldNew Scientist. “Within outer space days of returning, the algae began behaving normally again,

The survival of the algae adds credence to the “panspermia”theory,but researchers have yet to examine potential damage to the algal DNA. proximity  As New Scientist notes,  w It also provides Algae insight into whether humans could transport outer space plants to Algae  grow on other planets. hich suggests that comets and meteorites can bring life to sterile planets.
