Explanation:
In time stars trace lines through the night sky
on a rotating planet.
Taken over two hours or more, these digitally added consecutive exposures
were made with a camera and wide angle lens fixed to a tripod
near Orel farm, Primorsky Krai, Russia, planet Earth.
The stars trail in concentric arcs around the planet's
south celestial pole
below the scene's horizon, and north celestial pole off
the frame at the upper right.
Combined, the many short exposures also bring out the pretty star
colours.
Bluish trails are from stars hotter than Earth's Sun,
while yellowish trails are from cooler stars.
A long time ago this tree
blossomed, but now
reveals the passage of time in the wrinkled and weathered lines
of its remains.
