Unexplained Martian Glow Captured by Satellite

The European Space Agency's Trace Gas Orbiter satellite has captured a mysterious glow on the night side of Mars, separate from the previously observed green light emission during the day. Researchers have discovered that the night glow is caused by the recombination of oxygen atoms generated in the summer atmosphere, which then reunite with CO2 molecules and emit visible light. This finding provides valuable insights into Mars' upper atmosphere and its seasonal changes. Additionally, a glow in the ultraviolet light spectrum, believed to be due to nitric oxide molecules, was also detected. Future missions to Mars may capture images of these light emissions, offering further understanding of the planet.
