Sometimes even the dark dust of interstellar space has a serene beauty. One such place occurs toward the constellation of Taurus. The filaments featured here can be found on the sky between the Pleiades star cluster and the California Nebula. This dust is not known not for its bright glow but for its absorption and opaqueness. Several bright stars are visible with their blue light seen reflecting off the brown dust. Other stars appear unusually red as their light barely peaks through a column of dark dust, with red the color that remains after the blue is scattered away. Yet other stars are behind dust pillars so thick they are not visible here. Although appearing serene, the scene is actually an ongoing loop of tumult and rebirth. This is because massive enough knots of gas and dust will gravitationally collapse to form new stars — stars that both create new dust in their atmospheres and destroy old dust with their energetic light and winds.
中文翻譯:
在星際空間的黑暗塵埃中，有時能看見一種寧靜的美。這樣的地方位於金牛座的方向。這些特徵的絲狀結構，位於七姊妹星團（Pleiades）和加州星雲（California Nebula）之間。這些塵埃並不以明亮的光芒著稱，而是以其吸收與不透明聞名。幾顆明亮的星星散發著藍光，映射在棕色的塵埃上。而另一些星星則呈現出不尋常的紅色，因為它們的光線僅能穿透一條黑暗塵埃的柱子，留下的紅色是經過藍色光線散射後的顏色。還有一些星星被如此厚重的塵埃柱遮掩，以至於在此無法見到。
雖然這個場景看似寧靜，實則是一個持續的動盪與重生的循環。這是因為足夠大且密集的氣體和塵埃團塊將會因重力而崩潰，形成新的星星——這些新星不僅在其大氣中產生新塵埃，還以其強大的光和風來摧毀舊塵埃。
