Mars appears to be belching a large amount of gas that indicates microbes living on the planet. NASA's Curiosity rover has discovered high amounts of methane in Martian air. Methane gas is found on Earth that is usually produced by living things-microbes known as methanogens. NASA acknowledged the detection of methane but called it an early science result. The team will continue to analyze the data before confirming results.
