英仙座分子云中的星塵
Stardust in the Perseus Molecular Cloud

星塵雲飄過這片深邃的天空,穿過約 850 光年外的英仙座分子云。在近 4 度寬的視場中,反射著嵌入的年輕恆星光線的塵埃星雲格外顯眼。反射星雲 NGC 1333 帶有特有的藍色,在靠近中心的位置非常顯眼。赫比格-哈羅天體發出的對比鮮明的紅色光芒,即從新近形成的恆星中噴射出的噴流和受衝擊的發光氣體,散佈在塵埃瀰漫的大地上。雖然許多恆星正在分子云中形成,但在可見波長下,大部分恆星都被瀰漫的塵埃遮擋住了。NGC 1333 周圍的混亂環境可能與我們的太陽在 45 億年前形成時的環境相似。按照英仙座分子云的估計距離,這個宇宙場景將跨越大約 80 光年。 成長相簿:阿特拉斯彗星(G 3 )
原文:Clouds of stardust drift through this deep skyscape, across the Perseus molecular cloud some 850 light-years away. Dusty nebulae reflecting light from embedded young stars stand out in the nearly 4 degree wide field of view. With a characteristic bluish color reflection nebula NGC 1333 is prominent near center. Hints of contrasting red emission from Herbig-Haro objects, the jets and shocked glowing gas emanating from recently formed stars, are scattered across the dusty expanse. While many stars are forming in the molecular cloud, most are obscured at visible wavelengths by the pervasive dust. The chaotic environment surrounding NGC 1333 may be similar to one in which our own Sun formed over 4.5 billion years ago. At the estimated distance of the Perseus molecular cloud, this cosmic scene would span about 80 light-years. Growing Gallery: Comet ATLAS (G3)
