Egyptian news vision: - The US Space Agency (NASA) said that chemical reactions in the upper atmosphere are behind the transformation of the color of Mars from red to green.

The NASA orbiting vehicle "Maven" has recorded green pulses on Mars, but it is unlikely that astronauts will see it because it is visible only by ultraviolet rays, and it is not possible to see it with the naked eye.

And every evening, the upper atmosphere flashes softly in ultraviolet light, as the sun sets and temperatures drop to minus 62 degrees Celsius and below.

The discovery could help create a more detailed picture of Mars' weather, helping the first manned voyages to the Red Planet.

The researchers explained that the first manned mission to Mars will need better predictions than what is currently available to avoid wild winds and storms that can last for weeks, according to the British newspaper, "Daily Mail".

To reach this discovery, a team of researchers mapped the atmosphere of the red planet, for the first time, using data from the Maven spacecraft.

The greenish glow resembles the similar flares seen on Earth and Venus - initially observed by the European Space Agency's Mars Express mission in 2003.

The green glow, according to the study, occurs when nitrogen and oxygen atoms combine to form nitric oxide particles, causing small bursts of ultraviolet light to be released in the process.

As on Earth, the glow is influenced by the seasons, for example, night glow appears to be brighter at the peak of the planet's northern and southern winters.
