Explanation:
Real castles aren't this old.
And the background galaxy is even older.
Looking a bit like an alien castle, the pictured rock spires are called
hoodoos and are likely millions of years old.
Rare, but found around the world,
hoodoos
form when dense rocks slow the
erosion of
softer rock underneath.
The
pictured hoodoos survive in the
French Alps and are named
Demoiselles
Coiffцes -- which translates to English as
"Ladies with Hairdos".
The background galaxy is part of the central
disk of our own
Milky Way galaxy and contains
stars that are typically billions of years old.
The photogenic
Cygnus sky region -- rich in
dusty
dark clouds and red
glowing nebulas --
appears just above and behind the hoodoos.
The featured image
was taken in two stages: the foreground was captured during the evening
blue hour,
while the background was acquired from the same location later that night.
