Incredible Airglow

Sep. 2, 2015

On Sept. 1st, astrophotographer Yuri Beletsky hiked into the Atacama Desert of Chile for a deep exposure of the Milky Way. He got that and much more. "There was a stunning display of red airglow," he says. It surrounded the Milky Way like a celestial bulls-eye:

Airglow is aurora-like phenomenon caused by chemical reactions in the upper atmosphere. Human eyes seldom notice the faint glow, but It can be photographed on almost any clear dark night, anywhere in the world.

The curious thing about Beletsky's photo is not the presence of airglow, but rather its color--red. Airglow is usually green, the color of light from abundant oxygen atoms in a layer 90-100 km high. Where does the red come from? Instead of oxygen, less abundant hydroxyl ions (OH-) can produce the required color. These ions exist in a thin layer 85 km high where gravity waves impress the red glow with a dramatic rippling structure.

"It was a truly special night," says Beletsky. "Pure tranquility."

Details:
Under a Flaming Sky ... What is that you see on the image ?! No, these are not red clouds as one might think. This is incredibly bright airglow in the upper atmosphere ! One of the nights here in Atacama desert was truly special and we witnessed simply stunning scene under the stars. The Milky Way nicely aligned passing through the zenith, while some clouds were climbing up from beneath. Pure tranquility.

Himalayan magical night

2014-7-25

Gamba County, Xizang, China is at 4600 meters altitude. Bordering Sikkim and India, surrounded by the Himalayas in three directions. In addition to the familiar spring constellation, photos showed amazing wavy red airglow, which reminds me of a friend's pictures of red airglow outbreak from last year in Yunnan.

I'm jealous of people that can see auroras, let alone airglows. Also, those who can see the Milky Way with their naked eye are pretty OP too.
