一对活跃形成的年轻恒星高速流出的分子气体在红外光下闪耀，在詹姆斯韦伯太空望远镜的NIRcam图像中显示出它们自己。这些年轻的恒星被编号为HH（赫比格-哈罗）46/47，它们位于一个黑暗的星云中，在可见光下基本上是不透明的。这一对位于NIRcam图像中突出的红色衍射峰的中心。它们的高能恒星喷流延伸了近一光年，深入到黑暗的星际物质中。这个年轻的恒星系统相对较近，距离船帆座1140光年，是一个用韦伯红外望远镜探索的诱人天体。

High-speed outflows of molecular gas from a pair of actively forming young stars shine in infrared light, revealing themselves in this NIRcam image from the James Webb Space Telescope. Cataloged as HH (Herbig-Haro) 46/47, the young stars are lodged within a dark nebula that is largely opaque when viewed in visible light. The pair lie at the center of the prominent reddish diffraction spikes in the NIRcam image. Their energetic stellar jets extend for nearly a light-year, burrowing into the dark interstellar material. A tantalizing object to explore with Webb's infrared capabilities, this young star system is relatively nearby, located only some 1,140 light-years distant in the nautical constellation Vela.
