Explanation:
In trying times, stars still
trail in the night.
Taken on March 14, this night skyscape
was made by combining 230 exposures each 15 seconds long
to follow the stars' circular paths.
The camera was fixed to a tripod on an isolated terrace
near the center of Ragusa, Italy, on the island of Sicily.
But the night sky was shared around
the
rotating planet.
A friend to celestial navigators and astrophotographers alike
Polaris, the north star,
makes the short bright trail
near the center of the concentric
celestial
arcs.
