這可能看起來像一把雙刃光劍,但這兩股宇宙噴流實際上是從你附近星系的一顆新生恆星向外噴射的。根據哈勃太空望遠鏡的影像資料,這幅令人驚歎的場景橫跨約半光年的赫比格-哈羅 24 (HH 24 ),距離獵戶座 B 分子云複合體的恆星苗圃約 1300 光年或 400 皮秒。HH 24 的中央原恆星被冷塵埃和氣體包圍著,形成一個旋轉的吸積盤。當吸積盤中的物質落向年輕的恆星天體時,就會升溫。對立的噴流沿著系統的旋轉軸噴出。這些狹長的高能噴流穿過該區域的星際物質,沿其軌跡產生了一系列發光的衝擊鋒。
原文: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.
