你看到馬的頭了嗎？其實你看到的不是有名的馬頭星雲，而是一個需要更深的影像才能看得清的淡星雲。這幅圖片中的主要部分是一個叫IC 4592的反射星雲。反射星雲由非常細小的塵埃組成，通常看上去是黑暗的，但當它們反射附近星星的明亮光芒時，就會顯示出美麗的藍色。在這個情況下，反射光的主要來源是一顆位於馬的眼睛的星星。這顆星是Nu Scorpii的一部分，這是指向蠍子座（Scorpius）的亮星系統之一。圖片中央下方還可以看到一個名為IC 4601的第二反射星雲，圍繞著兩顆星星。這幅圖片是在卡塔爾的Sawda Natheel拍攝的。

Do you see the horse’s head? What you are seeing is not the famous Horsehead nebula toward Orion, but rather a fainter nebula that only takes on a familiar form with deeper imaging. The main part of the here-imaged molecular cloud complex is reflection nebula IC 4592. Reflection nebulas are made up of very fine dust that normally appears dark but can look quite blue when reflecting the visible light of energetic nearby stars. In this case, the source of much of the reflected light is a star at the eye of the horse. That star is part of Nu Scorpii, one of the brighter star systems toward the constellation of the Scorpion (Scorpius). A second reflection nebula dubbed IC 4601 is visible surrounding two stars just below the image center. The featured picture was taken from Sawda Natheel in Qatar.
