這張宇宙快照使用窄帶濾光片拍攝,在天鵝座範圍內的視場寬度是滿月的兩倍多。它突出顯示了一個環狀星雲的明亮邊緣,這個星雲是由電離氫氣和氧氣的光輝所描繪的。在該區域廣闊的星際雲層中,這些複雜、發光的弧線是被來自天狼射線恆星 WR 134 的風捲起的物質外殼的一部分,WR 134 是畫面中心附近最亮的恆星。據估算,WR 134 的距離約為 6000 光年,因此畫面的寬度超過 100 光年。大質量的沃爾夫射線恆星在強大的恆星風中脫落外包層,以驚人的速度消耗掉核燃料,並在壯觀的超新星爆炸中結束大質量恆星演化的最後階段。恆星風和最後的超新星為星際物質提供了豐富的重元素,這些重元素將被融入後代恆星中。
原文:Made with narrowband filters, this cosmic snapshot covers a field of view over twice as wide as the full Moon within the boundaries of the constellation Cygnus. It highlights the bright edge of a ring-like nebula traced by the glow of ionized hydrogen and oxygen gas. Embedded in the region's expanse of interstellar clouds, the complex, glowing arcs are sections of shells of material swept up by the wind from Wolf-Rayet star WR 134, brightest star near the center of the frame. Distance estimates put WR 134 about 6,000 light-years away, making the frame over 100 light-years across. Shedding their outer envelopes in powerful stellar winds, massive Wolf-Rayet stars have burned through their nuclear fuel at a prodigious rate and end this final phase of massive star evolution in a spectacular supernova explosion. The stellar winds and final supernova enrich the interstellar material with heavy elements to be incorporated in future generations of stars.
