NGC 602 ：來自韋伯望遠鏡的恆星與星柱
NGC 602: Stars Versus Pillars from Webb
發表日期：2024-10-29
恆星正在摧毀星柱。更具體地說，影像中心的一些新形成的恆星正在發出高能量的光，將周圍星柱中的氣體和塵埃蒸發掉。與此同時，星柱本身仍在努力形成新的恆星。整個環境就是星團 NGC 602 ，這一新景象是由韋伯太空望遠鏡以多種紅外色彩拍攝的。相比之下，翻轉影像顯示的是哈勃太空望遠鏡之前拍攝的可見光下的同一星團。NGC 602 位於小麥哲倫雲（SMC）的外圍附近，小麥哲倫雲是銀河系的一個小型衛星星系。 按照小麥哲倫雲的估計距離，這張照片的跨度大約為 200 光年。此外，還可以看到各種誘人的背景星系--大部分位於邊緣--它們至少在數億光年之外。
原文：The stars are destroying the pillars. More specifically, some of the newly formed stars in the image center are emitting light so energetic that is evaporating the gas and dust in the surrounding pillars. Simultaneously, the pillars themselves are still trying to form new stars. The whole setting is the star cluster NGC 602, and this new vista was taken by the Webb Space Telescope in multiple infrared colors. In comparison, a roll-over image shows the same star cluster in visible light, taken previously by the Hubble Space Telescope. NGC 602 is located near the perimeter of the Small Magellanic Cloud (SMC), a small satellite galaxy of our Milky Way galaxy. At the estimated distance of the SMC, the featured picture spans about 200 light-years. A tantalizing assortment of background galaxies are also visible -- mostly around the edges -- that are at least hundreds of millions of light-years beyond.
