A bit higher in the atmosphere (at altitudes of 300 to 400 km ), collisions with oxygen atoms produce red auroras. Milky Way on left side of image....SARS Arc.
Algae releasing oxygen as a by-product during photosynthesis. Breathe that clean air.
Algae, photosynthetic organisms and plants are the only organisms on the earth that can naturally produce oxygen. Take them away and we humans and life as we know cannot survive RIP.
Amounts of nitrogen and oxygen varies by altitude. This affects the colors of an aurora.
The decay of oxygen above 200 km produces red while below 200 green is produced. Below 100 km not enough atomic oxygen exists to have an effect.
Nitrogen produces blue and violet when it decays at the middle altitudes and magenta at the lowest altitudes.

I have so many to upload. I'll try to upload everything.
This is a college work for my photography class. We should take portrait photos.
I developed and printed everything.

It is cold, dark, dry and isolated with very little oxygen to breathe in the air, but the unique location makes Concordia station in Antarctica an attractive place for scientists to conduct research. The aurora australis that adds colour to this picture is a well-deserved bonus for the crew of 13 who are spending the winter months cut off from friends and family.
For nine months, no aircraft or land vehicles can reach the station, temperatures drop to –80°C and the Sun does not rise above the horizon for 100 days. Living and working in these conditions is similar in many respects to living on another planet and ESA sponsors a medical doctor to run research for future space missions.
The first astronauts to land on another planet might even see a similar beautiful spectacle illuminating the skies. Auroras appear when radiation from the Sun interacts with the atmosphere and almost all planets in the Solar System have auroras of some sort.
Read about the crew’s life at the end of the world on the Concordia blog.

A Community Matron came to the English for Speakers of Other Languages class today and talked about health matters. She tested our blood oxygen levels - mine was OK as were all the rest of the group. She also tested our blood sugar levels - mine was the lowest at 3.8 … my daughter says that I must eat more chocolate :)
Airman 1st Class Christopher Garrison performs liquid oxygen servicing at Atlantic City Air National Guard Base, N.J. Liquid oxygen is primarily used for aviator breathing. Garrison is an F-16C Fighting Falcon crew chief assigned to the 177th Aircraft Maintenance Squadron with the New Jersey Air National Guard. (U.S. Air National Guard photo/Tech. Sgt. Matt Hecht)

Thanks, gracias, gràcies everyone for your thoughts and good wishes on the last photo, you're the best!
He's at home and doing well, it was a really minor surgery, and the photo looked much more dramatic than reality, for sure!
So sorry if I scared or made you sad or queasy, but on the other hand it's good to know that it made you feel something. That's why photography is for, don't you think?
Well, going to try to catch up during this weekend, I'll do my best but you didn't stop uploading this days!!!!! So I have a loooot of photos to visit.
