Explanation: In this evocative night scene a dusty central Milky Way rises over the ancient Andean archaeological site of Yacoraite in northwestern Argentina. The denizens of planet Earth reaching skyward are the large Argentine saguaro cactus currently native to the arid region. The unusual yellow-hued reflection nebula above is created by dust scattering starlight around red giant star Antares. Alpha star of the constellation Scorpius, Antares is over 500 light-years distant. Next to it bright blue Rho Ophiuchi is embedded in more typical dusty bluish reflection nebulae though. The deep night skyscape was created from a series of background exposures of the rising stars made while tracking the sky, and a foreground exposure of the landscape made with the camera and lens fixed on the tripod. In combination they produce the single stunning image and reveal a range of brightness and color that your eye can’t quite perceive on its own.

说明: 在这幅夜空景观里，满是尘埃的银河盘面，悬在阿根廷西北安地斯山雅科瑞帖考古遗址的上空。影像里，这个干旱地区伸向天空的地球住民，则是阿根廷当地原生的树形大仙人掌。上空的不寻常泛黄反射星云，源自尘埃散射红巨星心宿二的星光。距离500多光年远的心宿二，是天蝎座最明亮的α星。不过，它附近泛蓝的明亮心宿增四，就包覆在较典型的泛蓝反射星云里。这片深空夜景，组合了一系列记录背景星空的照片，以及使用三脚架与相机拍摄的前方地景。所组合出的这幅精采影像，呈现了肉眼难以分辨的亮度及色泽变化。 （Yacoraite site 雅科瑞帖遗址）
