德国上空的流星与极光

Meteors and Aurora over Germany

Explanation: 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.

说明: 这是个不寻常的夜晚。首先，这星期稍早从8月11日过渡到12日的这个夜晚，落在英仙座流星雨的极大期附近。因此，当来自斯威夫特-塔特尔彗星的碎片穿入地球的大气层时，就会产生划过长空的流星。而更不寻常的是，德国中部的夜空，甚至会发出紫色的辉光。这种红蓝色的辉光，则是数天前由太阳喷出的大群粒子所诱发的极光。此次的极光磁暴极为强烈，就连在北半球的美国德州及意大利都能看到极光。这幅摄于德国 恩瑟镇的精彩主题影像，是由在26分钟期间拍摄的7张照片叠合而成。英仙座流星雨每年的8月都会如期降临，但要在这么偏南的地点见到极光，不但罕见而且难以预测。
