水滴裡的星系

A Little Drop of Galaxy

Explanation: A drop of water seems to hold an entire galaxy in this creative macro-astrophotograph. In the imaginative work of cosmic nature photography a close-up lens was used to image a previously made picture of a galaxy, viewed through a water drop suspended from a stem. A favorite of many telescope-wielding astroimagers, the galaxy is the Andromeda Galaxy, also known as M31. About 100,000 light-years across that majestic galaxy’s spiral arms and dust lanes are curved and distorted in the image contained in the centimeter-sized droplet. Andromeda is some 2.5 million light-years distant, but this project was still carried out while spending time indoors.

说明：在这幅颇有创意的微距天文影像里，水滴看似容纳了整个星系。为了创作出这张富想象力的天文影像，近焦镜头是一颗挂在树枝上的水滴，用以透视拍摄先前拍下的星系照片。而这个星系，则是许多拥有望远镜的天文学家热爱的仙女座星系（M31）。这个跨幅约100,000光年的宏伟星系，其螺旋臂及尘埃带，在这颗宽约一公分的水滴映像下，扭曲且变形。仙女座星系座落2百50万光年之外，不过这次的摄影作业全在室内完成的。
