June 7, 2013:  Every summer, something strange and wonderful happens high above the north pole.  Ice crystals begin to cling to the smoky remains of meteors, forming electric-blue clouds with tendrils that ripple hypnotically against the sunset sky.  Noctilucent clouds—a.k.a. "NLCs"--are a... Read More
