Explanation:
What's happening over that castle?
While waiting for the Moon to rise last month in
Thurso,
Scotland,
amateur astrophotographer Stewart Watt took a three minute
exposure of the background stars.
The above image was the surprising result.
Patchy clouds in front of the rising moon created
crepuscular rays
streaming across the night sky in spectacular fashion.
In the foreground is a stone tower from
Thurso Castle, a 12th century fortress
augmented in the 17th century.
Above the
crepuscular
moon rays are stars, many from the
constellation of the Lion
(Leo).
Visible to the right of the tower is the planet Saturn.
