在這個不尋常的夜晚,天空中發生了什麼?在這段長達 4 . 5 小時的 360 度全景影片中,最引人注目的可能是粉紅色和紫色的極光。這是因為在 5 月 11 日的這個夜晚,全世界都因極光而聞名。隨著夜幕降臨,極光帶閃閃發光,銀河系的中心帶升起,恆星隨著地球在其下方的自轉而移動。 這裡同時拍攝到的是極光上方一條罕見的紅色光帶:一條特區弧線,僅有輕微變化。地平線下的閃光是由駛過的汽車造成的,而天空中移動的光點則是衛星和飛機。 這段影片是用四臺攝像機從中國新疆拍攝的。
原文:What's happening in the sky this unusual night? Most striking in the featured 4.5-hour 360-degree panoramic video, perhaps, is the pink and purple aurora. That's because this night, encompassing May 11, was famous for its auroral skies around the world. As the night progresses, auroral bands shimmer, the central band of our Milky Way Galaxy rises, and stars shift as the Earth rotates beneath them. Captured here simultaneously is a rare red band running above the aurora: a SAR arc, seen to change only slightly. The flashing below the horizon is caused by passing cars, while the moving spots in the sky are satellites and airplanes. The featured video was captured from Xinjiang, China with four separate cameras.
