This dramatic beacon in the darkness over the #mountains of Spitsbergen, #Norway is a #solar #eclipse, an #astronomical #phenomenon that occurs when the #Earth, #moon, and sun are in a straight line. During a solar eclipse, the #air temperature decreases, the sky darkens, and sometimes #flowers close their petals. #photooftheday #nationalgeographic #photography #photo #nature 📷 @natgeo / Isabelle Bacher
