[:ja]ランディ・ブレズニク宇宙飛行士がISSから撮影したオーロラの動画です。オーロラは、太陽からのプラズマ粒子が惑星の磁力線に沿って極地方に向かって加速し、大気中の粒子と衝突して光っている現象です。このため、オーロラは高緯度地域でしか見るのが難しいのです。
My first aurora, ever! Looks like a fluorescent green cloud of cosmic smoke wafting over our planet. In a word- Fantasmal! #SpaceVideosRock pic.twitter.com/1kSraXWAqT

[Earthview Wonders][Video] No.318: Aurora
Astronaut Randy Bresnik captured from ISS beautiful aurora. Auroras are produced when the magnetosphere is sufficiently disturbed by the solar wind (charged particles in the form of electrons and protons) precipitate into the upper atmosphere. The resulting ionization and excitation of atmospheric constituents emits light of varying color and complexity. Thus an aurora is predominantly seen in the high latitude (Arctic and Antarctic) regions.
