這張宇宙快照的視野範圍超過滿月直徑的兩倍,拍攝於高空的天鵝座範圍內。該影像使用天文窄帶濾光片拍攝,突顯了環狀星雲明亮的邊緣,其輪廓由電離的氫和氧氣發出的光芒勾勒而成。 這些複雜而發光的弧形結構嵌入該區域廣闊的星際雲中,是沃爾夫-拉葉星WR 134 (影像中心附近最亮的恆星)所產生的恆星風捲起的物質殼層的一部分。據測算,WR 134 距離我們約 6 , 000 光年,因此這張望遠鏡拍攝的影像跨度超過 100 光年。 質量巨大的沃爾夫-拉葉星透過強勁的恆星風剝離外層包層,以驚人的速度耗盡了核燃料,最終以壯觀的超新星爆發結束其大質量恆星演化的最後階段。它們的恆星風和最終的超新星爆發為星際物質注入了重元素,這些元素將被融入未來幾代恆星之中。
原文:This cosmic snapshot covers a field of view over twice as wide as the full Moon within the boundaries of the high-flying constellation Cygnus. Made using astronomical narrowband filters, the image 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, the brightest star near image center. Distance estimates put WR 134 about 6,000 light-years away, making this telescopic 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 their final phase of massive star evolution in a spectacular supernova. Their stellar winds and final supernova explosion enrich the interstellar material with heavy elements to be incorporated in future generations of stars.
