Atomic oxygen produces red and green light when it decays after being excited. The red is seen tinging the top of auroras while the prominent green makes up the middle portion.

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.
My first session of hyperbaric oxygen therapy.
It was quite snug in the chamber with four of us in there. Three patients and one nurse. The next day there were five of us.
It was quite a surreal experience. After the door was closed the chamber became quite warm as it was pressurised to 2.3 atmospheres. We were offered boiled sweets and water to help us 'pop' our ears. I was advised to hold my nose and blow to pop my ears if sucking and swallowing didn't work.
When the right pressure had been achieved the nurse handed me my mask and fastened it for me. For the next 45 minutes I breathed pure oxygen while trying to read a book. But my mind kept wandering. We'd been told that it didn't matter how we breathed, just so long as we breathed. But should I take deep breaths? Would that get even more oxygen into me? If I stopped thinking about my breathing - and I wasn't sure I could as I could hear each breathe that I took and, I was sure, the breaths that the other patients were taking - if I didn't think about it might i forget to breathe? I have been known to forget to breathe but only when coming round from anaesthetic after an operation or after midazolam at the dentist. I didn't have any pains or feel strange in any way at the moment (other than my thoughts running around all over the place) but would that change as the minutes ticked away and the oxygen saturated my body? (It didn't).
Forty minutes later I heard a clang and a whooshing, sucking sound. A few minutes after that the nurse announced that it was break time and we could take our masks off. I was then given a cup of tea, two cream crackers and a slice of processed cheese. They had been delivered through a hatch in the wall and that had been the cause of the clang and the whoosh. After ten minutes the cups were collected, the nurse promised that "the second half goes a lot quicker" and I was helped to put my mask back on. At this point I realised that there was a small fancy clock on the outside ledge of the porthole to my right so I could see the time.
The nurse also told me that when the pressure is brought back to normal (known as 'going back up') she would use her own mask and at that point it would start to get cold. There was a blanket over the arm of my chair and I might want to put that on when she put her mask on.
So, one down, another 39 to go.
I wouldn't usually blur parts of photos but I don't think the chamber in the basement of a hospital can be considered a public place where people might expect their photograph to be taken and I didn't want to explain the whole flickr/365 thing which I would have had to do if I asked these guys for permission to put photographs of them on the internet.

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.

"7. I dipped my hands in forever. Touched you infinity. Treated you as if you were the last molecule of oxygen inside a gas chamber. I was good to you." - “Scars” by Rudy Francisco
Look, she's gonna fix the cowcatcher on that train. I am glad to see that she has tucked her hair up under her hat for safety.
Also no socks, I don't remember a Stankfoot epidemic in the 80's.
A factory operator, wearing a high-temperature resistant uniform.
He is holding a very long hollow iron pipe through which oxygen is pumped. The other end of the tube is pushed in the liquid metal. The oxygen coming out burns with the iron tube creating extremely high temperatures that melt the iron tube and help the liquid metal flow.
The liquid metal can be seen on his protective mask and iluminates the whole scene.
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.
