Real castles aren't this old. And the background galaxy is even older. Looking a bit like an alien castle, the pictured rock spires are called hoodoos and are likely millions of years old. Rare, but found around the world, hoodoos form when dense rocks slow the erosion of softer rock underneath. The pictured hoodoos survive in the French Alps and are named Demoiselles Coiffées -- which translates to English as "Ladies with Hairdos". The background galaxy is part of the central disk of our own Milky Way galaxy and contains stars that are typically billions of years old. The photogenic Cygnus sky region -- rich in dusty dark clouds and red glowing nebulas -- appears just above and behind the hoodoos. The featured image was taken in two stages: the foreground was captured during the evening blue hour, while the background was acquired from the same location later that night.?

真正的城堡沒有這么古老。而背景星系更古老。照片中的巖石尖頂看起來有點像外星人的城堡，它們被稱為hoodoos，可能有數(shù)百萬年的歷史。當稠密的巖石減緩下面較軟巖石的侵蝕時，會形成一種罕見的、但在世界各地都能找到的樹叢。照片中的烏鴉生活在法國阿爾卑斯山，取名為Demiselles Coiffees，英文翻譯為“有發(fā)型的女士”。背景星系是我們銀河系中心盤的一部分，包含通常有數(shù)十億年歷史的恒星。上鏡的天鵝座天空區(qū)域——富含塵土飛揚的烏云和紅光閃爍的星云——出現(xiàn)在胡德烏斯的正上方和后方。這張?zhí)厣珗D片分兩個階段拍攝：前景是在晚間藍色時段拍攝的，而背景是在當天晚些時候從同一地點拍攝的。
