從地球升起巨大的噴射閃電
Up from the Earth: Gigantic Jet Lightning

發表日期:2025-09-09
從地球上升起的是什麼?七月初,宇航員尼科爾-艾爾斯在國際空間站上環繞地球飛行時,看到了一種不同尋常的閃電從地球上升起:一個巨大的噴流。這股強大的噴流出現在紅白藍三色的圖片中心附近。巨型噴射閃電在過去 25 年中才為人所知。大氣噴流與雷暴有關,並向上延伸至地球的電離層。 畫面下部顯示的是夜晚的地球,地球稀薄的大氣層被氣輝染成綠色。城市的燈光時隱時現,但通常會在雲層中形成瀰漫的白光。 畫面頂部是漆黑夜空中遙遠的星星。巨型噴流的性質及其可能與其他型別的瞬態發光事件(TLEs)(如藍色噴流和紅色精靈)之間的聯絡仍然是活躍的研究課題。
原文:What's that rising up from the Earth? When circling the Earth on the International Space Station early in July, astronaut Nicole Ayers saw an unusual type of lightning rising up from the Earth: a gigantic jet. The powerful jet appears near the center of the featured image in red, white, and blue. Giant jet lightning has only been known about for the past 25 years. The atmospheric jets are associated with thunderstorms and extend upwards towards Earth's ionosphere. The lower part of the frame shows the Earth at night, with Earth's thin atmosphere tinted green from airglow. City lights are visible, sometimes resolved, but usually creating diffuse white glows in intervening clouds. The top of the frame reveals distant stars in the dark night sky. The nature of gigantic jets and their possible association with other types of Transient Luminous Events (TLEs) such as blue jets and red sprites remain active topics of research.
