你看到昨晚的极光了吗？几天前，这个问题与世界大部分地区息息相关，因为一场强大的极光风暴在远离地球两极的地方变得异常可见。原因是周二发生的一次巨大的x级太阳耀斑，向太阳系发射了高能电子和质子，并通过地球磁场与地球相连。这些粒子撞击地球大气层中的氧原子发出的红光弥漫在画面中，而垂直的条纹则在跳舞。这段特色视频是在意大利北部阿尔卑斯山脉山峰的科尔蒂纳丹佩佐拍摄的一小时延时视频。来自银河系的恒星点缀在背景中，而来自飞机和卫星的条纹点缀在前景中。太阳最近的剧烈活动可能会在未来一年左右的时间里继续在地球上空产生风景如画的极光。图集：2024年10月10日至11日的全球极光

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
