The Terraced Night
Long after sunset on January 25 an unusually intense red airglow floods this south-looking skyscape. The scene was recorded with a long exposure using a digital camera over Yunnan Province in southwest China. At best faintly visible to the eye, the lingering airglow is due to chemiluminescence
, the production of light through chemical excitation. Originating at an altitude similar to aurora, it can found around the globe
. The chemical energy is initially provided by the Sun's extreme ultraviolet radiation On this night, despite the luminous atmosphere, the band of the Milky Way clearly stretches above the horizon with bright star Sirius near the top of the frame. Both airglow and starry sky are beautifully reflected in region's watery Yuanyang rice terraces

<<Until recently, everyone agreed that domestic cats first appeared in ancient Egypt, about five thousand years ago. [However,] recent excavation of a 5,000 year-old village in Shaanxi has unearthed the bones of cats that seem to have been preying on rodents that were living in the village and raiding the villagers’ crops and food stores. The scientists were able to rely on a quirk of biochemistry that distinguished animals that had been eating mainly wild plants from those that had been getting their nutrition from [millet].>> - John Bradshaw: author of “Cat Sense: the feline enigma revealed”

What a lovely APOD. Both the sky and the Earth are terraced.

When you look up to the heavens, you see our Father.
When you look down, you see our Mother.
We are the Children, in between...
What an inspiring APOD....and quit a coincidence....I had Rice today....
That is some Sirius Red Glow.
Is it me or is that image rotated a few degrees clockwise?
Are the small points of light that appear very close to the surface of the terraced landscape reflections of the stars in the water flooding the rice paddies? The size and brightness matches the heavenly bodies above. At first, I took them to be fireflies (or something similar) until I zoomed in to the image enough.
Pretty (and) phenomenal.

This is a remarkable picture! At first glance I thought the skyglow was the aurora borealis. The reflection of the sky in the terraced rice paddies is truly lovely.
May all beings be happy, peaceful, and free.
With these glows looking like cirri the photographer may have felt himself like under a dome.
