8月12日，美国国家航空航天局（NASA）的WB-57F高空研究飞机在冰岛海岸上空追逐新月的影子，观察日全食。在5万英尺的高空，飞机沿着精确确定的日全食路径飞行，以最大限度地延长在月球阴影中的时间。飞船上的一套高分辨率相机能够从云层、尘埃和大气水蒸气上方记录日食数据，这些数据会干扰离地面更近的观测。这是从驾驶舱拍摄的飞行视频，捕捉到了日冕在日全食开始时出现的景象。在月亮的阴影下，天空显得很暗。在视频画面中，金星在中间偏左的位置闪耀，而木星和水星刚好在日食太阳的右侧可见。但在月亮的阴影照不到的远处地平线上，天空是明亮的。APOD的主要NASA网站正在迁移：从APOD .

Chasing the shadow of a New Moon, NASA’s WB-57F high altitude research aircraft took to the skies off the coast of Iceland on August 12 to observe a total solar eclipse. At 50,000 feet the aircraft was piloted along the precisely determined path of totality to maximize its time in the Moon’s shadow. A suite of high-resolution cameras on board was able to record eclipse data from above the clouds, dust, and atmospheric water vapor that interfere with observations made closer to the ground. This view from the cockpit, taken from an inflight video, captures the solar corona emerging at the beginning of totality. The sky appears dark in the shadow of the Moon. Venus is shining left of center in the video frame, while Jupiter and Mercury are just visible to the right of the eclipsed Sun. But the sky is bright along the distant horizon below, beyond the reach of the Moon's shadow. APOD's main NASA site is moving: From apod.nasa.gov to science.nasa.gov/apod
