A total solar eclipse is visible through the clouds as seen from Vagar on the Faeroe Islands, Friday, March 20, 2015. Apart from a few small breaks, a blanket of clouds in the Faeroe Islands blocked thousands of people there from experiencing the full effect of the total eclipse. (AP Photo/Eric Adams)
