在遙遠的宇宙裡，有一種叫做塵埃柱的神秘東西。它們就像星際中的山脈，因為它們比周圍的環境要密集。雖然它們堅強地存在著，但卻在一個非常嚴酷的環境中慢慢被侵蝕。這幅圖片是由哈勃太空望遠鏡拍攝的，展示了一個巨大的氣體和塵埃柱的末端，來自特里菲德星雲（Trifid Nebula，M20）。柱子的上方有一根較小的柱子指向天空，還有一束不尋常的噴流向左上方延伸。在圖片中的很多亮點，都是剛誕生的星星。而在小柱子的一旁，還有一顆星星，正在被一顆在圖片上方、光芒萬丈的星星的輻射慢慢剝奪周圍的氣體。那束噴流的長度幾乎有一光年遠，沒有外部的光照，這是看不見的。隨著這些柱子中的氣體和塵埃不斷揮發，這束噴流背後隱藏的星星源頭，可能會在接下來的兩萬年內被發現。
原文:
Dust pillars are like interstellar mountains. They survive because they are more dense than their surroundings, but they are slowly being eroded away by a hostile environment. Visible in the featured picture by the Hubble Space Telescope is the end of a huge gas and dust pillar in the Trifid Nebula (M20), punctuated by a smaller pillar pointing up and an unusual jet pointing to the upper left. Many of the bright dots are newly formed stars. A star near the small pillar’s end is slowly being stripped of its accreting gas by radiation from a tremendously brighter star situated off the top of the image. The jet extends nearly a light-year and would not be visible without external illumination. As gas and dust evaporate from the pillars, the hidden stellar source of this jet will likely be uncovered, possibly over the next 20,000 years. Explore the Universe: Random APOD Generator
