Explanation:
Have you ever seen a halo around the Moon?
Such 22 degree rings around the Moon -- caused by
ice crystals
falling in the
Earth's atmosphere -- are
somewhat rare.
OK, but have you ever seen a blue moon?
Given the modern definition of
blue moon -- the second full
moon occurring in a calendar month -- these are also rare.
What is featured above might therefore be considered doubly rare -- a
halo surrounding a
blue moon.
The featured image was taken late last month near
Zhongshan Station
in Antarctica.
Visible in the foreground are a power generating house and a
snowmobile.
What might seem to be stars in the background are actually illuminated snowflakes
near the camera.
