爆发火山上方的星空
Stars over an Erupting Volcano

Explanation: Mt. Etna has been erupting for hundreds of thousands of years. Located in Sicily, Italy, the volcano produces lava fountains over one kilometer high. Mt. Etna is not only one of the most active volcanoes on Earth, it is one of the largest, measuring over 50 kilometers at its base and rising nearly 3 kilometers high. Pictured erupting last month, a lava plume shoots upwards, while hot lava flows down the volcano’s exterior. Likely satellite trails appear above, while ancient stars dot the sky far in the distance. This volcanic eruption was so strong that nearby airports were closed to keep planes from flying through the dangerous plume. The image foreground and background were captured consecutively by the same camera and from the same location.

说明: 这幅影像的前景及背景，都是由同一部相机先后摄于相同地点。埃特纳火山已连续喷发了数十万年。位在意大利西西里岛的这座火山，喷出的熔岩喷泉超过1公里高。埃特纳峰除了是地球上最活跃的火山之一，也是最大者之一，基部宽50多公里，标高也接近有3公里。这幅摄于上个月爆发期间的埃特纳火山影像，记录了向上喷出的熔岩与从火山边坡泛流而下的炽热岩浆。除此之外，影像里还有可能是卫星曳出的迹线，以及散布在天空的遥远古老恒星。这次的火山喷发很强烈，所以不得不关闭邻近的数座机场，以免飞机穿过危险的火山尘。这幅影像的前景及背景，都是由同一部相机先后摄于相同地点。
