这是一个不寻常的夜晚。首先，8月11日和12日的夜空，也就是本周早些时候，出现在英仙座流星雨的高峰期附近。因此，当斯威夫特-塔特尔彗星的碎片撞击地球大气层时，流星划过了漆黑的夜空。更不寻常的是，至少在德国中部，夜空闪耀着紫色。这种红蓝色的色调是由于几天前太阳粒子爆炸造成的极光。这次极光风暴非常强烈，远在地球北半球的德克萨斯州和意大利都能看到。这张特色图片是在德国恩塞拍摄的26分钟的7次曝光合成的。英仙座流星雨每年8月都会出现，但在如此遥远的南方，极光更加不寻常，也更难以预测。画廊：2024年英仙座流星雨和极光
查看原文解释
This was an unusual night. For one thing, the night sky of August 11 and 12, earlier this week, occurred near the peak of the annual Perseid Meteor Shower. Therefore, meteors streaked across the dark night as small bits cast off from Comet Swift-Tuttle came crashing into the Earth's atmosphere. Even more unusually, for central Germany at least, the night sky glowed purple. The red-blue hue was due to aurora caused by an explosion of particles from the Sun a few days before. This auroral storm was so intense that it was seen as far south as Texas and Italy, in Earth's northern hemisphere. The featured image composite was built from 7 exposures taken over 26 minutes from Ense, Germany. The Perseids occur predictably every August, but auroras visible this far south are more unusual and less predictable. Gallery: Perseid Meteor Shower 2024 and Aurorae
