Bright swaths of red in the upper atmosphere, known as airglow, can be seen in this image taken from the International Space Station. NASA's ICON mission, with a planned launch for the summer of 2017, will observe how interactions between terrestrial weather and a layer of charged particles called the ionosphere create the colorful glow.

"Airglow over Alberta, Canada" (click here)
Green waves of airglow over Alberta, Canada.
I find the orange color of the air glow in Australia rather unusual. I think orange air glow is rare actually. Now, methane will burn orange if it doesn't have enough oxygen. The only other chemical that I am aware of that will burn orange is calcium chloride, but, it is a solid and not a gas. I haven't read anything about what gas in the southern hemisphere is burning orange instead of the expected usual hues.

On October 7, an astronaut aboard the International Space Station shot this photograph while orbiting at an altitude of more than 250 miles over Australia.
...The photo, (click here) taken over Australia, shows part of the ISS in the very forefront of the photo from where the photo was taken inside the station. Millions of stars are visible in the background past the Earth and the Earth below is indicated with a curved line along the horizon and more dim lights on the landforms and clouds below.
The airglow gave researchers some insight into how the atmosphere works, according to NASA. It can be useful to scientists because it gives them information about the way the particles in the atmosphere interact between the Earth and space. This can reveal findings about Earth and space weather as well.
Research into this part of the Earth and space is often done through the data from satellites but photos like the one from the station can also help researchers find out more about the part of space....
