在廣闊的星際空間中,閃耀著紅色光芒的氫-α氣體彷彿浸沒了這幅美麗的宇宙場景。這片景象涵蓋了約3度的天空,指向充滿星雲的蛇夫座,直朝我們的銀河系中心。前景中罩著的微薄塵埃雲被稱為LDN 234和LDN 204,是由美國天文學家貝佛莉·林茲於1962年編製的黑暗星雲目錄所確認的。Sh2-27本身是一個大型卻微弱的HII區域,圍繞著逃逸的O型恒星Zeta Ophiuchi。這個Zeta Oph的HII區域和LDN 234、LDN 204可能距離我們約500光年。以這個距離來看,這幅望遠鏡的畫面大約有25光年寬。
原文:
The diffuse hydrogen-alpha glow of emission region Sh2-27 fills this cosmic scene. The field of view spans nearly 3 degrees across the nebula-rich constellation Ophiuchus toward the central Milky Way. A Dark Veil of wispy interstellar dust clouds draped across the foreground is chiefly identified as LDN 234 and LDN 204 from the 1962 Catalog of Dark Nebulae by American astronomer Beverly Lynds. Sh2-27 itself is the large but faint HII region surrounding runaway O-type star Zeta Ophiuchi. Along with the Zeta Oph HII region, LDN 234 and LDN 204 are likely 500 or so light-years away. At that distance, this telescopic frame would be about 25 light-years wide.
