London, Oct 22 : A scientist has claimed to have found concrete evidence that confirms the detection of methane gas on Mars and also identifies key sources of the gas.
The scientist in question is Michael Mumma, of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, US.
While on Earth, methane is mostly biological in origin, on Mars, it could signal microbes living deep underground.
According to a report in Nature News, the latest work suggests that Martian methane is concentrated in both space and time.
At a handful of hotspots hundreds of kilometers across, plumes of methane bloom and dissipate in less than a year.
