獵戶座的搖籃
Orion's Cradle

在緋紅氫氣的搖籃中，獵戶座正孕育著新生恆星。這些恆星搖籃位於巨型獵戶座分子云複合體的邊緣，距離地球約 1500 光年。這幅精細影像橫跨著名星座中心約 12 度範圍，右下方可見大獵戶星雲——這是距離地球最近的大型恆星形成區。 這幅深度拼接影像還捕捉到頂部中央附近的火焰星雲與馬頭星雲。透過氫-α濾鏡獲取的影像資料為這幅廣角宇宙全景增添了更多奇觀：瀰漫的帶電原子氫氣絲縷，以及周邊巴納德環的部分割槽域。 儘管獵戶星雲及獵戶座眾多恆星肉眼可見，但星際間廣袤氣體的輻射微弱難測，即便透過望遠鏡觀測星雲密集區域亦難以捕捉。天象驚喜：APOD 在您生日當天展示了哪幅圖片？（ 1995 年後）
原文：Cradled in red-glowing hydrogen gas, stars are being born in Orion. These stellar nurseries lie at the edge of the giant Orion molecular cloud complex, some 1,500 light-years away. This detailed view spans about 12 degrees across the center of the well-known constellation, with the Great Orion Nebula, the closest large star-forming region, visible toward the lower right. The deep mosaic also includes, near the top center, the Flame Nebula and the Horsehead Nebula. Image data acquired with a hydrogen-alpha filter adds other remarkable features to this wide-angle cosmic vista: pervasive tendrils of energized atomic hydrogen gas and portions of the surrounding Barnard's Loop. While the Orion Nebula and many stars in Orion are easy to see with the unaided eye, emission from the extensive interstellar gas is faint and much harder to record, even in telescopic views of the nebula-rich complex.
