He who melts it
Astronomers finally figured out where the methane on Mars comes from. The inventory solves a mystery that has been initiated since the organic gas was first discovered on Mars in 2003 – but which later removed scientists who tried to measure and track it.
It turns out that an ice sheet on the Mars surface near Gale Crater, which may have once been a lake, is likely to yield by the planet's methane according to the research published Monday in the journal Nature Geoscience – and which could represent another puzzle in the mystery of whether the red planet
The research describes two studies, both isolated the same ice as the source of atmospheric methane by data from two spacecraft and simulations of the Martian the atmosphere.
It is worth noting that the data for these studies was collected in 201

The presence of methane is often proclaimed as a sign of life, but confirms that Mars has methane, is not quite the same as confirming that life exists there.
Instead, the combination of atmospheric methane near the source of water opens the possibility that life may have once existed – the researchers behind this new study determined the question of "where" in terms of martian methane, but their study does not cleave the surface of " why "or" how ".
