ASTRONOMY - King of Wings Hoodoo under the Milky Way

 2024 July 21

The band of the Milky Way runs across a night sky filled 
with stars. Colorful clouds are on the right horizon. A strange
rock structure appears in the image center with a base and 
an extended arm that seems to point to the colorful horizon.
Please see the explanation for more detailed information.

Explanation: This rock structure is not only surreal -- it's real. Perhaps the reason it's not more famous is that it is smaller than one might guess: the capstone rock overhangs only a few meters. Even so, the King of Wings outcrop, located in New MexicoUSA, is a fascinating example of an unusual type of rock structure called a hoodooHoodoos may form when a layer of hard rock overlays a layer of eroding softer rock. Figuring out the details of incorporating this hoodoo into a night-sky photoshoot took over a year. Besides waiting for a suitably picturesque night behind a sky with few clouds, the foreground had to be artificially lit just right relative to the natural glow of the background. After much planning and waiting, the final shot, featured here, was taken in May 2016. Mimicking the horizontal bar, the background sky features the band of our Milky Way Galaxy stretching overhead.
