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.
