IC 4592 :藍馬頭反射星雲
IC 4592: The Blue Horsehead Reflection Nebula

你看到馬頭了嗎?你所看到的並非位於獵戶座方向的著名馬頭星雲,而是一個較暗淡的星雲,只有透過更深層的成像才能顯現出熟悉的形狀。這張影像中所示分子云複合體的主要部分是反射星雲IC 4592 。 反射星雲由極其細微的塵埃構成,通常呈現暗色,但在反射附近高能恆星的可見光時,會呈現出相當藍的色調。在此案例中,大部分反射光的來源是位於馬眼位置的一顆恆星。該恆星屬於天蠍座Nu 星,這是天蠍座(Scorpius)方向上較明亮的恆星系統之一。 在影像中心正下方,可見另一個被稱為IC 4601 的反射星雲環繞著兩顆恆星。這張特色圖片拍攝於卡達的索瓦達·納提爾(Sawda Natheel)。 拼圖星雲:每日天文謎題
原文: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.
