        "http://www.w3.org/2000/01/rdf-schema#comment" : [ "Night clouds or noctilucent clouds are tenuous cloud-like phenomena that are the \"ragged edge\" of a much brighter and pervasive polar cloud layer called polar mesospheric clouds in the upper atmosphere, visible in a deep twilight. They are made of crystals of water ice. Noctilucent roughly means night shining in Latin. They are most commonly observed in the summer months at latitudes between 50° and 70° north and south of the equator." ] ,
