您看到昨晚的極光了嗎?幾天前,這個問題在世界許多地方都很重要,因為在離地球兩極很遠的地方就能看到異常強烈的極光風暴。原因是週二發生了一次巨大的 X 級太陽耀斑,它向太陽系發射了高能電子和質子,並透過我們星球的磁場與地球相連。 這些粒子撞擊地球大氣層高處的氧原子後發出的紅光瀰漫了整個畫面,垂直條紋也隨之舞動。影片展示了從科爾蒂納丹佩佐(Cortina d'Ampezzo)俯瞰義大利北部阿爾卑斯山峰的一小時延時攝影。 銀河系的星星點綴著背景,飛機和衛星的條紋點綴著前景。在未來一年左右的時間裡,太陽近期的高活躍度很可能會繼續在地球上空產生如詩如畫的極光。 相簿: 2024 年 10 月 10 / 11 日期間的全球極光
原文:Did you see last night's aurora? This question was relevant around much of the world a few days ago because a powerful auroral storm became visible unusually far from the Earth's poles. The cause was a giant X-class solar flare on Tuesday that launched energetic electrons and protons into the Solar System, connecting to the Earth via our planet's magnetic field. A red glow of these particles striking oxygen atoms high in Earth's atmosphere pervades the frame, while vertical streaks dance. The featured video shows a one-hour timelapse as seen from Cortina d'Ampezzo over Alps Mountain peaks in northern Italy. Stars from our Milky Way Galaxy dot the background while streaks from airplanes and satellites punctuate the foreground. The high recent activity of our Sun is likely to continue to produce picturesque auroras over Earth during the next year or so. Gallery: Global aurora during October 10/11, 2024
