National Geographic Travelさんのインスタグラム写真 - (National Geographic TravelInstagram)「Photo by @Chrisburkard | It’s these lights that keep me coming back– I’ve been to Iceland over 30 times (and have many more trips there planned) and this spectacle is one of the reasons I’m so drawn to the small island country. There’s something special about its people and much of the landscapes themselves are breathtaking as well, but standing below this natural phenomenon is inexplicable. The scientific term for this display is an aurora, specifically an Aurora Borealis for the northern hemisphere, which is pictured above. On the simplest level, these bright lights are actually collisions between electrically charged particles emitted from the sun and gaseous particles in the Earth’s atmosphere. I always seek situations where the outdoors makes me feel small, and knowing this event stems from particles shot all the way from the sun makes me feel just about as small as I can imagine. It was extra humbling to take in this view with Heiðar Logi, an Icelandic local who has spent much time under these colors, but is still just as awe-struck as I am every time he sees them.」6月19日 7時00分
