In July 2015, the New Horizons spacecraft made history when it became the first robotic explorer to conduct a flyby of Pluto. This was followed by another first, when the NASA mission conducted the first flyby of a Kuiper Belt Object (KBO) on 31 December 2018 – which has since been named Arrokoth.

The European Space Agency (ESA) has just announced that its ExoMars Trace Gas Orbiter (TGO) has identified a long-suspected “green glow” around Mars. The green glow is due to the interaction of sunlight with atoms and molecules in Mars’ atmosphere. To date, we’ve only observed the phenomenon around one other planet: Earth. Now, the scientists who’ve discovered the Red Planet’s green glow say it could help us better understand the planet’s atmosphere. And how to land safely on its surface.

Futurism reported on the finding, which was outlined in a paper recently published in the journal, Nature. According to the paper, this discovery marks the first time scientists have observed the “day glow” and “night glow” that generate the “green line” around Earth around Mars. Or any other planet. The discovery also stands as long sought-after confirmatory evidence of predictions regarding the Martian atmosphere, which date back 40 years.
