这可能看起来像一把双刃的光剑，但这两束宇宙喷流实际上是从你附近星系的一颗新生恒星向外发射的。这幅令人惊叹的景象是由哈勃太空望远镜的图像数据构成的，横跨赫比格-哈罗24 （HH 24）约半光年，距离猎户座B分子云复合体的恒星孕育室约1300光年或400秒差距。HH 24的中心原恒星隐藏在视线之外，被冷尘埃和气体包围，被压扁成旋转的吸积盘。当圆盘上的物质落向年轻的恒星物体时，它就会升温。相反的喷流沿着系统的旋转轴喷射出去。穿过该区域的星际物质，这些狭窄的高能喷流沿着它们的路径产生了一系列发光的激波锋。

This might look like a double-bladed lightsaber, but these two cosmic jets actually beam outward from a newborn star in a galaxy near you. Constructed from Hubble Space Telescope image data, the stunning scene spans about half a light-year across Herbig-Haro 24 (HH 24), some 1,300 light-years or 400 parsecs away in the stellar nurseries of the Orion B molecular cloud complex. Hidden from direct view, HH 24's central protostar is surrounded by cold dust and gas flattened into a rotating accretion disk. As material from the disk falls toward the young stellar object, it heats up. Opposing jets are blasted out along the system's rotation axis. Cutting through the region's interstellar matter, the narrow, energetic jets produce a series of glowing shock fronts along their path.
