A MYSTERY IN THE MESOSPHERE

This summer, something strange has been happening in the mesosphere--a layer of Earth's atmosphere so high that it nearly touches space. The mesosphere is the realm of noctilucent clouds, electric-blue glowing forms that are seeded by meteor smoke. Lately, these clouds have been glowing more brightly than usual. What's happening up there? Visit today's edition of   fSpaceweather.comor the answer.

happening in the mesosphere.
