NGC 3572 的年輕恆星旁有熾熱的氣體和黑暗的塵埃雲。 這是一個美麗的發射星雲和星團,位於船底座的南部天空。 來自 NGC 3572 的恆星位於望遠鏡框架的中央偏上位置,該星團的估計距離為 9000 光年,直徑約為 100 光年。 可見的星際氣體和塵埃以哈勃調色盤的顏色顯示,它們是星團原生分子云的一部分,本身被編入 Gum 37 。星雲中密集的物質流受到恆星風和輻射的侵蝕,明顯地從能量旺盛的年輕恆星中流出。 它們很可能是正在形成的恆星的位置,其形狀讓人聯想到 IC 410 的蝌蚪星--北方的觀天者對它更為熟悉。 在未來的幾千萬年到幾億年裡,星團中的氣體和恆星將被引力潮汐和劇烈的超新星爆炸驅散,結束大質量星團恆星的短暫生命。
原文:This cosmic skyscape features glowing gas and dark dust clouds alongside the young stars of NGC 3572. A beautiful emission nebula and star cluster, it sails far southern skies within the nautical constellation Carina. Stars from NGC 3572 are toward top center in the telescopic frame that would measure about 100 light-years across at the cluster's estimated distance of 9,000 light-years. The visible interstellar gas and dust, shown in colors of the Hubble palette, is part of the star cluster's natal molecular cloud, itself cataloged as Gum 37. Dense streamers of material within the nebula, eroded by stellar winds and radiation, clearly trail away from the energetic young stars. They are likely sites of ongoing star formation with shapes reminiscent of the Tadpoles of IC 410 -- better known to northern skygazers. In the coming tens to hundreds of millions of years, gas and stars in the cluster will be dispersed though, by gravitational tides and by violent supernova explosions that end the short lives of the massive cluster stars.
