尘埃喧天的星云

Dusty NGC 1333 is seen as a reflection nebula in visible light images, sporting bluish hues characteristic of starlight reflected by dust. But at longer infrared wavelengths, the interstellar dust itself glows - shown in red in this false-color Spitzer Space Telescope image. The penetrating infrared view also shows youthful stars that would otherwise still be obscured by the dusty clouds which formed them. Notably, greenish streaks and splotches that seem to litter the region trace the glow of cosmic jets blasting away from emerging young stellar objects as the jets plow into the cold cloud material. In all, the chaotic scene likely resembles one in which our own Sun formed over 4.5 billion years ago. NGC 1333 is a mere 1,000 light-years distant in the constellation Perseus.


翻译:NGC 1333是个到处都是尘埃的反射星云，在可见光波段，它带着尘埃反射星光所造成的蓝色色调。但在较长波长的红外光，这朵星际尘埃云其实也会发出辉光，这幅伪彩色的斯必泽太空望远镜影像就是一个见证。在这张高穿透力的红外光影像中，可以见到通常被尘埃云所遮蔽的年轻恒星。更为特殊的是散在各处的绿色线纹和斑纹，它们呈现出从新生天体射出的喷流及喷流冲撞冷云气物质的结果。这些纷乱的现象，很可能也会出现在45亿年前我们太阳初形成时的周围环境中。

哦！！！！

我不明白NGC是什么意思？！~~~
他代表的是什么呢

NGC是星云星团总表的英文简称，就像梅西叶星表用M表示一样。
