Explanation: The bird is bigger than the peak. Nicknamed for its avian shape, the Seagull Nebula is an emission nebula on the night sky that is vast, spanning an angle over five times the diameter of the full moon and over 200 light years. The head of the nebula is catalogued as IC 2177, and the star cluster under its right wing is catalogued as NGC 2343. Consisting of mostly red-glowing hydrogen gas, the Seagull Nebula incorporates some dust lanes and is forming stars. The peak over which this Seagull seems to soar occurs at Pinnacles National Park in California, USA. The featured image is a composite of long exposure images of the background sky and short exposure images of the foreground, all taken consecutively with the same camera and from the same location.

说明: 这只鸟比山峰大。形似飞禽的海鸥星云，是地球夜空中幅度广阔的发射星云，其张角是满月直径的5倍多，跨幅则超过200光年。此星云的头部之编录号是IC 2177，右翼下的星团之编录号为NGC 2343。海鸥星云的主要成分是会散发红光的氢气，其中并间杂着一些正在形成恒星的尘埃带。而这只看似高飞的海鸥下方之山峰，则是位于美国加利福尼亚州的尖顶国家公园之内。这幅主题影像，是由记录背景天空的长曝光照片及记录前景的短曝光照片组合而成，而所使用的照片皆是由相同的相机连续拍摄于同一地点。
