Astronomers found Mars & # 39; missing methane



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

Twin Studies

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

3, while the studies that did not detect any methane were conducted in 2018. However, the recent study focused on the upper atmospheric re-researchers behind it admitting that there may be basic sources of methane, which they simply missed. And since one of the new studies used data from the curiosity of the curiosity over the martial landscape, it is likely that the methane was simply too sparse to measure from an orbital instrument.

Follow That Smell

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 ".
