在明亮的英仙座歐米茄星附近有一個巨大的雲霧狀區域,這就是宇宙對比的研究物件。 望遠鏡捕捉到的這個由塵埃、氣體和恆星組成的五彩斑斕的複合體,在大約 1000 光年外的英仙座分子云邊緣的天空上橫跨約 3 度。被反射著星光的藍色塵埃光環包圍著的是英仙座歐米茄本身,它位於中心偏左的位置。在它的正下方,是詹姆斯-韋伯太空望遠鏡(James Webb Space Telescope)最近探索到的有趣的年輕星團 IC 348 。右上方是星際塵埃雲巴納德 3 號的輪廓,在氫氣瀰漫的淡紅色光暈中,巴納德 3 號顯得晦暗不明。當然,宇宙塵埃也往往會把新形成的恆星和年輕的恆星天體或原恆星隱藏起來,不讓光學望遠鏡發現。按照英仙座分子云的估計距離,這個視場的跨度大約為 50 光年。
原文:A great nebulous region near bright star omicron Persei offers this study in cosmic contrasts. Captured in the telescopic frame the colorful complex of dust, gas, and stars spans about 3 degrees on the sky along the edge of the Perseus molecular cloud some 1000 light-years away. Surrounded by a bluish halo of dust reflected starlight, omicron Persei itself is just left of center. Immediately below it lies the intriguing young star cluster IC 348 recently explored by the James Webb Space Telescope. In silhouette against the diffuse reddish glow of hydrogen gas, dark and obscuring interstellar dust cloud Barnard 3 is at upper right. Of course the cosmic dust also tends to hide newly formed stars and young stellar objects or protostars from prying optical telescopes. At the Perseus molecular cloud's estimated distance, this field of view would span about 50 light-years.
