Washington.- A group of researchers determined that conditions in the lunar surface were sufficient to support single life forms 4 billion years ago, according to a study published today. In the journal Astrobiology.

In addition, scientists concluded in their report that there was another window of livability there are about 3,500 million of them. years during a peak of l & # 39; volcanic activity of the Luna

During both periods, the main author, Dirk Schulze-Makuch, astrobiologist at the University of Washington, showed that Luna released large amounts of superheated volatile gases, including steam water from inside
This degassing, according to researchers could have formed pools of 39; liquid water on the surface lunar and an atmosphere dense enough to remain there for millions of years
If liquid water and a significant atmosphere were present in Luna early for long periods, we believe that the lunar surface would have been at least temporarily habitable
The work of Schulze-Makuch and Ian Crawford, of the University of London, is based on the s results of recent space missions and the analysis of samples of rocks and lunar soils that prove that Luna is not "as dry" as it was thought before.
In 2009 and 2010, an international team of scientists discovered hundreds of millions of tons of ice in the Luna . In addition, there is evidence of a large amount of water in the lunar mantle that would have been deposited at a very early stage.
It is also likely that the Earth's satellite According to the authors, Schulze-Makuch would have further explained that: "At that time, a magnetic field capable of defending life forms on the surface of "Deadly solar winds" would have been protected. Life in Luna could have come largely as she did on Earth, but the most likely scenario would have been caused by a meteorite.
The most premature evidence of life on Earth comes from fossilized cyanobacteria that are between 3,500 and 3,800 million years old. Meanwhile, the solar system was dominated by the impacts of giant meteorites and frequent
It is possible that meteorites containing simple organisms such as cyanobacteria were expelled from the surface of the Earth and reached the Moon [19659014] Schulze-Makuch acknowledged, however, that determining whether life arose in Luna or was transported from elsewhere "can only be addressed by a future aggressive exploration program lunar . "
A promising research track for any future space mission would be to obtain samples of deposits from the period of greatest volcanic activity to see if they contain water or d & # 39; other possible markers of life.
Similarly, experiments could be performed in simulated lunar environments. Earth and the International Space Station to see if microorganisms can survive under environmental conditions that are supposed to exist They were on the Moon
