[:ja]Jeff Williams宇宙飛行士がISSから撮影した、夜光雲の向こうに三日月が見えている幻想的な画像です。映画スターウォーズとかに出てきそうな風景ですね。
夜光雲は、夏の高緯度地域（50~70度）の中間圏（地上50~80km）に日の出前や日没後に観測される、地球上で最も高い高度に発生する雲です。高緯度地域であるスウェーデン・ウプサラの地上で見られた美しい夜光雲もご覧下さい。

[Earthview Wonders] No.43: Noctilucent Clouds and Crescent Moon
Jeff Williams captured this so surreal image of crescent moon behind noctilucent clouds. It might well be used in Star Wars scenes.
Noctilucent clouds are clouds formed in the mesosphere(50-80km from the ground) during summer of high latitude regions(50-70°) and are often called the highest clouds in Earth’s atmosphere. This is the link to the amazing noctilucent clouds taken in Uppsala, Sweden.
