This is the secret of Methane Gas On Mars

Astronomers finally figured out where the methane on Mars is coming from. The finding resolves a mystery that’s been ongoing since the organic gas was first detected on Mars in 2003. It turns out that an ice sheet on Mars’ surface near Gale Crater, which may have once have been a lake, is likely giving off the planet’s methane, according to research published Monday in the journal Nature Geoscience.
