NASA found signs of life on Mars

NASA's Curiosity's self-propelled Mars detector has detected traces of methane - an organic gas form normally produced by living organisms - stating the first evidence of the body lives outside the earth.

The new discovery is published in the journal Science, in which Curiosity's laser-directed spectroscopy (TAS) analyzes chemical gas samples and detects abnormally high and high levels of methane in some places. Fire.

Low levels of methane are explained by the way that the sun rays degrade organic matter that are likely to be deposited by supernovae. However, other records in an area of ​​300m2 show that the amount of methane increased by 10 times within 60 days on Mars. When Curiosity goes a few kilometers away, such high methane levels no longer appear.

Dr. Paul Mahaffy of NASA said: 'The most interesting thing is that at some point, methane has come and gone. At this point we are really hard to confirm but there is a lot of emissions detected. We should keep our mind open '.

Dr Mahaffy said scientists did not rule out anything including the sign or evidence of stored methane, suggesting the possibility of ancient life in this place. NASA announced that with additional records from Curiosity and it is possible that isotope tests will provide evidence that whether the methane is derived from biological origin.

Life is the main source of methane production on earth but there are also other non-biological methane sources, including from the phenomenon of celestial collisions. However, no recent collisions are reported near Gale Crate - a large crater formed by collisions about 3.5 to 3.8 billion years ago on the red planet. Curiosity began exploring this area since 2012.
