ESA’s ExoMars Trace Gas Orbiter has detected glowing green oxygen in Mars’ atmosphere – the first time that this emission has been seen around a planet other than Earth. “One of the brightest emissions seen on Earth stems from night glow. More specifically, from oxygen atoms emitting a particular wavelength of light that has never been seen around another planet,” says Jean-Claude Gérard of the Université de Liège, Belgium, and lead author of the new study published in Nature Astronomy. “However, this emission has been predicted to exist at Mars for around 40 years – and, thanks to TGO, we’ve found it.”
