Explanation: 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.

说明: 在这幅由韦伯太空望远镜近红外光相机所拍摄的影像里，起源自一对形成中年轻恒星的高速分子气体外泛流，散发出明亮的红外辉光。而这对编录号为HH（Herbig-Haro）46/47的年轻恒星，则镶在一团几乎不透可见光的黝黑星云里。在这幅近红外光影像里，这对恒星位于醒目的泛红衍射芒的中心； 而它们强烈的恒星喷流伸展了将近1光年，并穿透黝黑的星际物质。对韦伯望远镜的红外光相机来说，位在航帆座内、距离只有1,140光年远的这个年轻的恒星系统，是非常值得探索的标的。
