Explanation:
Why are these large stones here?
One the more famous stone circles is the
Duddo Five Stones of
Northumberland,
England.
Set in the open near the top of a modest incline,
a short hike
across empty fields will bring you to
unusual
human
-sized stones
that are unlike anything surrounding them.
The grooved, pitted, and deeply
weathered surfaces of the soft
sandstones
are consistent with being placed about 4000 years ago --
but placed for
reasons now unknown.
The featured image -- a composite of two consecutive images
taken from the same location --
was captured last October under a starry sky when the
Earth
was passing near Mars, making the
red planet unusually large and bright.
Mars remains
visible at sunset, although increasingly
close to the horizon over the next few months.
