ELT 和銀河系
ELT and the Milky Way

南方冬季的銀河橫跨夜空。從正南方向看去,網路攝像頭記錄的景象是在當地時間 3 月 11 日接近午夜時,智利阿塔卡馬沙漠中部乾燥、黑暗的天空中。在漫射星光的優美弧線下方,是強大銀河系的衛星星系,也被稱為大麥哲倫雲和小麥哲倫雲。前景是歐洲南方天文臺的 40 米級超大望遠鏡(ELT)。該望遠鏡位於 Cerro Armazones 海拔 3000 米的山頂,正在建設中,有望成為地球上最大的 "天眼"。
原文: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.
