ESA's vessel ExoMars Trace Gas Orbiter (TGO) have observed a bright green glow around the red planet.
It writes the European space agency ESA in a press release, according to Science.dk, where you can also see a photo of the phenomenon, as it takes out on the Ground.
It is due to oxygen, and is otherwise only known from one other planet, namely the Earth, where the phenomenon of also often shows itself as the northern lights.
The green glow is due to the sun's rays collide with the atoms and molecules in the air, creating a faint, green light.
TGO spacecraft has hovered around the red planet since 2016, among other things, to look for the green 'halo' on Mars.
the Researchers have in 40 years that it would be there, but it is only now that they can demonstrate the existence.
- Previous observations had not caught any green tinge around Mars, so we decided to divert [TGO's instruments] to point at the ’edge’ of Mars, like the perspective, you look at the pictures of the Earth taken from The International Space station, says co-author Ann Carine Vandaele of the Institut Royal d'Aéronomie Spatiale de Belgique, Belgium, in a press release, writing Science.dk.
the Glow from the planets atmosphere could provide scientists with important information about how the atmospheric conditions are on the planet.
Observations on Mars fits in with the earlier theoretical models, but not with the actual glow, we have seen around the Earth [...]. It may mean that we have much more to learn about how oxygen atoms behave, which is extremely important for our understanding of the atom and quantum physics, says lead author on the study, Jean-Claude Gérard from the Université de Liège, Belgium, in the press release, according to Science.dk.
