Milky Way Casting Shadows - Chile Astrophotography - San Pedro de Atacama Celestial Explorations Star Tour

We know the Sun and Moon cast shadows. But if Milky Way is bright enough to throw shadows? This is panorama from San Pedro de Atacama Celestial Explorations Star Tour. On the photo you can see shadows of trees cast by the Milky Way!

Based on Bortle scale of night sky's brightness this is one of the darkness sky on Earth - Scale 1 - Excellent dark-sky site - The Scorpius and Sagittarius region of the Milky Way casts obvious diffuse shadows on the ground. Not so often can see something like this!

Green and red airglow is noticeable close to the horizon. The brightest "star" in the center is actually Jupiter.
