A sign of life beyond Earth

Signs of life survival in extraterrestrial planets from the results of the "virus" detection on the crater.

International scientists have discovered that the population of the virus is able to live and thrive in an almost oxygen-free environment in Lake Diamante, located inside a giant crater, higher than sea level 4,700. m in Argentina.

The water in Lake Diamante has almost no oxygen but has an alkaline and very high arsenic content, exactly like the original Earth environment before the oxygen-containing atmosphere surrounds it.

Arsenic content in the lake is 2,000 times higher than the amount allowed in human drinking water.The salinity of lake water is 5 times higher than seawater so although the temperature in the lake is always below the freezing water temperature, the ice does not form in the lake.

Scientists believe that if the viruses live and thrive well in this environment, especially under very strong ultraviolet conditions, they can live in harsh environments like Mars and other planets. out of Earth.That is a sign oflife beyond Earth.

The lead researcher, Maria Eugenia Farias, also emphasized the discovery of the lives of viruses that opened the door to look at life on Earth in the past.

In addition, Argentinian scientists are investigating the possibility of using the bacterium's strong ultraviolet anti-ultraviolet advantages to produce drugs such as sunscreens, antioxidants and enzymes.
