Explanation: What strange world is this? Earth. In the foreground of the featured image are the Pinnacles, unusual rock spires in Nambung National Park in Western Australia. Made of ancient sea shells (limestone), how these human-sized picturesque spires formed remains unknown. In the background, just past the end of the central Pinnacle, is a bright crescent Moon. The eerie glow around the Moon is mostly zodiacal light, sunlight reflected by dust grains orbiting between the planets in the Solar System. Arching across the top is the central band of our Milky Way Galaxy. Many famous stars and nebulas are also visible in the background night sky. The featured 29-panel panorama was taken and composed in 2015 September after detailed planning that involved the Moon, the rock spires, and their corresponding shadows. Even so, the strong zodiacal light was a pleasant surprise.

澳大利亚尖峰石阵上空的银河

说明: 这片奇异的世界是什么？地球是也。这幅主题影像的前景为尖峰石阵，是位在西澳大利亚南邦国家公园内的不寻常尖顶石柱。成份为远古海贝(石灰岩)、高度与人相当的这些美丽尖顶石柱，其成因不明。在背景中，紧贴在中间那根尖峰石顶端的天体是明亮的眉月。月亮周围的魅异晕光主要是黄道光，是被在太阳系行星之间公转的尘埃所反射的阳光。而影像上端的拱弧，则是我们银河系的中央盘面。此外，在背景的夜空中，还可见到许多著名的恒星和星云。这幅由29张照片接成的全景影像，是在仔细考虑月亮、石柱和其影子等因素之后，拍摄和组合于2015年9月。虽然如此，但特别明亮的黄道光仍然是意外的惊喜。
