在廣闊的獵戶座分子雲複合體中，幾個明亮的藍色星雲特別顯眼。在圖中央，你可以看到兩個最著名的反射星雲——這些是被明亮的嵌入恆星反射光線的塵雲。在圖的中心，有著名的M78星雲，它已經被登錄超過200年。位於其左上方的是不太知名的NGC 2071。天文學家們仍在研究這些反射星雲，以更好地理解內部恆星是如何形成的。整個紅光是來自擴散的氫氣，涵蓋了獵戶座複合體的大部分，它跨越了獵戶座星座。在更大的複合體中，距離我們約1,500光年的地方，還有獵戶星雲、馬頭星雲和巴納德環——在上方左邊的白色帶子中部分可見。

In the vast Orion Molecular Cloud complex, several bright blue nebulas are particularly apparent. Pictured here in the center are two of the most prominent reflection nebulas – dust clouds lit by the reflecting light of bright embedded stars. The more famous nebula is M78, in the image center, cataloged over 200 years ago. To its upper left is the lesser known NGC 2071. Astronomers continue to study these reflection nebulas to better understand how interior stars form. The overall red glow is from diffuse hydrogen gas that covers much of the Orion complex that spans much of the constellation of Orion. Nearby in the greater complex, which lies about 1,500 light years away, are the Orion Nebula, the Horsehead Nebula, and Barnard’s Loop — partially seen here as the white band on the upper left.
