從羅傑斯、坎貝爾和懷特奧克 1960 年的天文星表中可以看到,RCW 85 發射區在南方夜空中閃耀,位於明亮的半人馬座阿爾法星和貝塔星之間。在大約 5000 光年的距離上,這個由發光的氫氣和塵埃組成的朦朧星際雲非常微弱。但在這幅由 28 小時的窄帶和寬頻曝光組成的宇宙天景圖中,可以看到 RCW 85 內部沿輪廓分明的邊緣的詳細結構。這個誘人的星雲被稱為 "魔鬼塔",讓人聯想到其他恆星託兒所中的戲劇性形狀,在那裡,氣體和塵埃雲被新生恆星產生的高能風和輻射鵰刻而成。在 RCW 85 的估計距離上,這個望遠鏡框架將跨越大約 100 光年。
原文:From the 1960 astronomical catalog of Rodgers, Campbell and Whiteoak, emission region RCW 85 shines in southern night skies between bright stars Alpha and Beta Centauri. About 5,000 light years distant, the hazy interstellar cloud of glowing hydrogen gas and dust is faint. But detailed structures along well-defined rims within RCW 85 are traced in this cosmic skyscape composed of 28 hours of narrow and broadband exposures. Suggestive of dramatic shapes in other stellar nurseries where natal clouds of gas and dust are sculpted by energetic winds and radiation from newborn stars, the tantalizing nebula has been called the Devil's Tower. This telescopic frame would span around 100 light-years at the estimated distance of RCW 85.
