Methane is not there almost at all.
The presence of this gas indicates the possible existence of species on the red planet.
Scientists upset by the news of the disappearance of methane from the atmosphere of Mars, and we intend to carry out additional checks to investigate the situation. For the first time this gas on the red planet discovered in 2004 with the help of the Mars Express. Ten years later, the equipment picked up more methane than before.
This news has excited scientists because its presence gives hope to find intelligent life on Mars, or at least primitive organisms. New studies of the planet of the apparatus TGO showed that there is almost no methane at all.
Astronomers believe the gas is entering the atmosphere of Mars from external sources. Physicists are now inclined to believe that the formation of methane on the red planet is cyclic. That is growth followed by decline.
In the atmosphere of Mars are always of organic matter coming from the outside. According to scientists, one of them should be formed methane. Why this happens is currently unclear. TGO will function on Mars until 2022, so physicists have the time to answer their questions about the cosmic object.
