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 known informally as Mystic Mountain, these pillar’s appearance is dominated by the dark dust even though it is composed mostly of clear hydrogen gas. Dust pillars such as these are actually much thinner than air and only appear as mountains due to relatively small amounts of opaque interstellar dust. About 7,500 light-years distant, the featured image was taken with the Hubble Space Telescope, digitally reprocessed by an industrious amateur, and highlights an interior region of Carina which spans about three light years. Within a few million years, the stars will likely win out completely and the entire dust mountain will be destroyed. Did you Know: This week is International Dark Sky Week?

✨ 星星與塵埃在卡瑞納星雲中對峙，而星星正逐漸獲勝。更準確地說，剛誕生的巨大恆星所釋放的能量光與風正蒸發並驅散它們形成的塵埃星際雲。這些被稱為「神秘山脈」的塵埃柱，外觀上雖然以暗黑塵埃為主，但主要成分卻是透明的氫氣。這些塵埃柱其實比空氣薄很多，因為相對較少的跡象星際塵埃讓它們看起來像山一樣。這幅圖片位於距離地球約7,500光年的位置，是由哈勃太空望遠鏡拍攝的，並由一位勤奮的愛好者進行數字重製，突顯了卡瑞納內部一個大約三光年的區域。再過幾百萬年，這些星星可能會獲勝，整個塵埃山脈將會被摧毀。
