Evidence of Life Found on Mars

NASA unveiled evidence that confirms for the first time beyond doubt, the presence of organic substances in the Martian soil.

NASA’s Curiosity rover did not find any evidence of ancient or modern microbial life on the red planet, but made two discoveries that bring this potential closer in the future.

In addition to organic matter, it has also been confirmed that not only a basic organic chemical compound, methane, exists in the Martian atmosphere, probably originating from an unknown source on the surface or underground of the planet.

Michael Meyer, lead scientist for NASA’s Mars Exploration Program, at NASA Headquarters, said:

“Are there signs of life on Mars?



We don’t know, but these results tell us we are on the right track.”
