三裂星云的中心发生了什么？三裂星的名字来源于三条显著的尘埃带。不透明的尘埃山出现在底部附近，而其他黑色的尘埃细丝则贯穿整个星云。中心附近可见的一颗大质量恒星产生了三裂星云的大部分辉光。编号为M20的三裂星云只有大约30万年的历史，是已知的最年轻的发射星云之一。这个正在形成恒星的星云位于大约9000光年外的射手座（人马座）。照片中的区域跨度约为20光年。传送门宇宙：随机APOD生成器

What's happening at the center of the Trifid Nebula? Three prominent dust lanes that give the Trifid its name all come together. Mountains of opaque dust appear near the bottom, while other dark filaments of dust are visible threaded throughout the nebula. A single massive star visible near the center causes much of the Trifid's glow. The Trifid, cataloged as M20, is only about 300,000 years old, making it among the youngest emission nebulas known. The star forming nebula lies about 9,000 light years away toward the constellation of the Archer (Sagittarius). The region pictured here spans about 20 light years.
