A truly powerful image generates questions.
The incredible night photos and time-lapse movies NASA has been sharing with us provoke questions about our planet. That thin-yellow atmospheric line separating earth from space, for example, that we see in all of the night shots provokes two questions: (1) how thick is this line? and (2) why is this line colored the way it is?
The visible yellow and green/blue capped line represents atmosphere reaching ~100km above the surface of the earth. The colors are not reflected light, and not pollution, but rather are light generated from the components in the atmosphere itself. Yes, the atmosphere gives off its own light, in a chemiluminescent process called "airglow" or "night glow."
I have written a blog to accompany this video that explains the various colors of "Night Glow" and discusses the Aurora as well. I hope you find this blog a useful companion to understanding what you are seeing.

This is the story of a beautiful forest, a forest that is as it should be but like so many before it, its future may be a another tree farm. Elphinstone Logging Focus volunteers take local residents on a tour of The Forest in an effort to have what has become, an endangered species protected.
In 1968 Roger Smith ate a peach during a break from work. When he was finished he took out a pocketknife and began carving the peach pit into a tiny pig. 43 years later the retired meter reader and cattle rancher from Culloeka, Tennessee has carved hundreds of peach seeds into hummingbirds, stingrays, gospel choirs, entire villages, even a baseball stadium with 100+ figures. “Given enough time,” says Smith, “I don’t think there is anything you can’t make out of a peach seed.”
Roger Smith’s unique art, inspiring talent, and fascinating life are the subject of a short (11 minute) documentary by filmmaker Stewart Copeland. The explores Smith’s process as well as his inspirations and presents a thoughtful portrait of a self-taught artist who’s distinctive art is as much a part of his rural Southern landscape as it is a reflection of it.
Roger Smith has been featured in the books TRADITION: TENNESSEE LIVES AND LEGACIES by Robert Cogswell and WEIRD TENNEESSEE by Roger Manley. His peach seed…
Just think about it… What if you were trapped under something heavy and the mouse was out of your reach? Scary, right? That's exactly why we have these keyboard shortcuts so you can still use Vimeo until the help arrives.
