It's the first time the emission has been seen on a world beyond Earth.

The atmosphere of Mars has a distinct green glow, just like Earth's.
The European Space Agency's Trace Gas Orbiter (TGO) spotted an emerald glow in Mars' wispy atmosphere, marking the first time the phenomenon has been spotted on a world beyond Earth, a new study reports.
"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," study lead author Jean-Claude Gérard, of the Université de Liège in Belgium, said in a statement.
"However, this emission has been predicted to exist at Mars for around 40 years — and, thanks to TGO, we’ve found it," Gérard said.
