國際空間站穿越太陽
International Space Station Crosses the Sun

通常情況下,只有在夜間才能看到國際空間站。 國際空間站(ISS)在圍繞地球執行的過程中緩慢地劃過夜空,大約每月一次,在許多地方都能看到國際空間站的亮點。 國際空間站只有在日落之後或日出之前才能被看到,因為它是透過反射的陽光發光的--一旦國際空間站進入地球的陰影,它就會消失在人們的視線中。國際空間站在白天唯一可見的情況是它從太陽正前方經過。在這種情況下,國際空間站的移動速度非常快,只有短時間曝光的相機才能將國際空間站的輪廓定格在太陽背景上。這張照片正是如此--它實際上是一個月前在西班牙聖費柳-德-布瓦薩勒拍攝的一組照片,拍攝時間恰到好處。 這組影像後來與另一張突出活動太陽紋理的影像結合在一起,其中包括邊緣的幾個太陽突出物。 天體驚喜在您生日那天,APOD 刊登了哪張照片?

原文:Typically, the International Space Station is visible only at night. Slowly drifting across the night sky as it orbits the Earth, the International Space Station (ISS) can be seen as a bright spot about once a month from many locations. The ISS is then visible only just after sunset or just before sunrise because it shines by reflected sunlight -- once the ISS enters the Earth's shadow, it will drop out of sight. The only occasion when the ISS is visible during the day is when it passes right in front of the Sun. Then, it passes so quickly that only cameras taking short exposures can visually freeze the ISS's silhouette onto the background Sun. The featured picture did exactly that -- it is actually a series of images taken a month ago from Sant Feliu de Buixalleu, Spain with perfect timing. This image series was later combined with a separate image highlighting the texture of the active Sun which included several Sun's prominences around the edge.
