A green glow in the martian night

Amazing stuff!

"... The nightglow serves as a tracer of atmospheric processes. It can provide a wealth of information about the composition and dynamics of a region of the atmosphere difficult to measure, as well as the oxygen density. It can also reveal how energy is deposited by both the Sun’s light and the solar wind – the stream of charged particles emanating from our star. ..."

ESA - A green glow in the martian night When future astronauts explore Mars’s polar regions, they will see a green glow lighting up the night sky. For the first time, a visible nightglow has been detected in the martian atmosphere by ESA’s ExoMars Trace Gas Orbiter (TGO) mission.
