南方冬季的银河在夜空中蔓延。3月11日当地午夜时分，在智利中部阿塔卡马沙漠干燥、黑暗的天空中，向南拍摄的网络摄像机画面。在漫射星光的优美弧线下方，是强大的银河系的卫星星系，也被称为大小麦哲伦星云。前景是欧洲南方天文台40米级超大望远镜（ELT）的所在地。在海拔3000米的塞罗·阿玛佐斯山顶上，ELT正在建设中，它将成为地球上最大的天空之眼。

The southern winter Milky Way sprawls across this night skyscape. Looking due south, the webcam view was recorded near local midnight on March 11 in dry, dark skies over the central Chilean Atacama desert. Seen below the graceful arc of diffuse starlight are satellite galaxies of the mighty Milky Way, also known as the Large and Small Magellanic clouds. In the foreground is the site of the European Southern Observatory's 40-metre-class Extremely Large Telescope (ELT). Under construction at the 3000 metre summit of Cerro Armazones, the ELT is on track to become planet Earth's biggest Eye on the Sky.
