德國上空的流星和極光
Meteors and Aurora over Germany

這是一個不同尋常的夜晚。首先，本週早些時候的 8 月 11 日和 12 日的夜空接近每年英仙座流星雨的高峰期。因此，流星劃過漆黑的夜空，斯威夫特-塔特爾彗星上的小碎片墜入地球大氣層。更不尋常的是，至少在德國中部，夜空呈現出紫色。這種紅藍色是幾天前太陽粒子爆炸產生的極光造成的。這次極光風暴非常強烈，在地球北半球最南端的德克薩斯州和義大利都能看到。 這幅特寫圖片是由德國恩斯 26 分鐘內拍攝的 7 次曝光合成的。英仙座流星雨每年八月都會出現，但在如此遙遠的南方能看到的極光則更不尋常，也更難預測。 相簿： 2024 年英仙座流星雨和極光
原文：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
