M 16 :創星之柱
M16: Pillars of Star Creation
發表日期:2024-10-22
這些黑暗的星柱看似具有破壞性,其實它們正在創造恆星。 這張鷹星雲的柱狀捕捉照片結合了哈勃太空望遠鏡拍攝的可見光曝光和詹姆斯-韋伯太空望遠鏡拍攝的紅外影像,突出顯示了從分子氫氣體和塵埃柱中出現的蒸發氣團球(EGGs)。 這些巨型氣柱長度達數光年,密度極高,內部氣體在引力作用下收縮形成恆星。 在每個星柱的末端,明亮年輕恆星的強烈輻射會導致低密度物質沸騰,從而使高密度 EGG 的恆星苗圃暴露出來。 鷹星雲與疏散星團 M 16 有關,位於大約 7000 光年之外。 拼圖挑戰每日天文拼圖
原文:These dark pillars may look destructive, but they are creating stars. This pillar-capturing picture of the Eagle Nebula combines visible light exposures taken with the Hubble Space Telescope with infrared images taken with the James Webb Space Telescope to highlight evaporating gaseous globules (EGGs) emerging from pillars of molecular hydrogen gas and dust. The giant pillars are light years in length and are so dense that interior gas contracts gravitationally to form stars. At each pillar's end, the intense radiation of bright young stars causes low density material to boil away, leaving stellar nurseries of dense EGGs exposed. The Eagle Nebula, associated with the open star cluster M16, lies about 7000 light years away. Jigsaw Challenge: Astronomy Puzzle of the Day
