这是船底座星云中恒星与尘埃的对决，而恒星是赢家。更准确地说，来自大质量新形成恒星的高能光和风正在蒸发和分散它们形成的尘埃恒星托儿所。这些柱子位于船底座星云，位于一个非正式地称为神秘山的区域内，尽管它们主要由透明的氢气组成，但它们的外观主要由不透明的棕色尘埃组成。尽管一些尘埃柱看起来像火把，但它们的末端并没有着火，而是被附近的恒星照亮了。这张特色图片是用哈勃太空望远镜拍摄的，距离地球约7500光年，突出了船底座的一个内部区域，即HH1066，它跨越了近一光年。在几百万年内，恒星可能会完全胜出，尘埃火炬将完全蒸发。

It's stars versus dust in the Carina Nebula and the stars are winning. More precisely, the energetic light and winds from massive newly formed stars are evaporating and dispersing the dusty stellar nurseries in which they formed. Located in the Carina Nebula and inside a region known informally as Mystic Mountain, these pillars' appearance is dominated by opaque brown dust even though it is composed mostly of clear hydrogen gas. Even though some of the dust pillars look like torches, their ends are not on fire -- rather, they are illuminated by nearby stars. About 7,500 light-years distant, the featured image was taken with the Hubble Space Telescope and highlights an interior region of Carina known as HH1066 which spans nearly a light year. Within a few million years, the stars will likely win out completely and the dust torches will completely evaporate.
