Aurora Borealis Effect Spotted on Mars? What a New Discovery Reveals

We should consider ourselves so lucky to be living on Earth. Our planet is home to some of the most wonderful phenomenons from the Cosmos. For a long time, humanity believed that only on Earth we could find beautiful sights like Aurora Borealis, rain, and a lot more. But it turns out they were so wrong, and a new research proves it once more.

A faint green glow was spotted slightly above Mars, and it was due to the interaction between oxygen and the light received by the upper atmosphere from the Sun.

The glow was known to exist only on Earth

The astronomer Jean-Claude Gérard of the Université de Liège in Belgium conducted the new study for concluding the beautiful green ‘ring’ above Mars. He confirms that the phenomenon resembles the green glow we see on Earth.

Jean-Claude Gérard declared:

“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,

However, this emission has been predicted to exist at Mars for around 40 years – and, thanks to [ExoMars Trace Gas Orbiter], we’ve found it.”

The way the beautiful phenomenon occurs on Mars is not hard to understand at all: carbon dioxide gets separated from oxygen and carbon monoxide when solar radiation is striking the atmosphere of the Red Planet. The oxygen atoms are creating the green glow. The necessary data was gathered with the help of the ExoMars Trace Gas Orbiter.

While nightglow has previously been observed on other planets as well, the phenomenon that Jean-Claude Gérard and his colleagues have now observed within the atmosphere of Mars is what they call ‘dayglow,’ as it has a faint presence that makes it harder to detect.

The astronomers had published their research in Nature Astronomy.
