在紅色發光的氫氣中，有星星正在奮力誕生，這個美麗的地方叫做獵戶座。這些星星的搖籃位於巨大獵戶分子雲的邊緣，距離我們約有1500光年。我們看到的這幅廣闊的圖像大約寬12度，中央是知名的獵戶座星座，在右下角能看到最近的大型恆星形成區域—獵戶星雲。圖像的上方中央還包含了火焰星雲和馬頭星雲。使用氫-alpha濾鏡取得的數據，讓這幅宇宙畫面更加壯觀：充滿活力的原子氫氣體的纖細絲線和周圍的巴納德環（Barnard’s Loop）的一部分。雖然獵戶星雲和獵戶座的許多星星能用肉眼清楚看到，但大量的星際氣體發出的光則相對微弱，即使在望遠鏡下觀察這個星雲豐富的區域也相當困難。

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.
