Milky Way over the Australian Pinnacles

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.

澳洲尖石阵上空的银河

说明: 这是那颗怪异的行星啊?地 球 是也。这幅主题影像前景的尖石阵,是一群位于澳洲西部南邦国家公园内的不寻常尖顶石柱。这些成份为远古海贝(石灰岩)、大小与人类相当的石柱,其成因目前仍然是研究的课题。在影像背景里,紧贴在尖顶石柱顶的是明亮的蛾眉月。而月亮周围的魅异辉光,主要来自太阳系行星间的尘埃微粒反射阳光所产生的黄道光。影像顶缘的拱形光弧,则是我们银河系的中央盘面。此外,夜空背景里更点缀着许多著名的恒星与星云。这幅摄于2015年9月、由29张照片拼接而成的主题影像,拍摄前经过仔细规划,考量了月亮的位置、尖石柱的排列,以及它们所投射的影子。尽管如此,拍照当时格外明亮的黄道光,仍是意外的惊喜。
