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.

這可能看起來像一把雙剃刀光劍，但這兩道宇宙噴流其實是從一顆新生星星發射出來的，距離你不遠的星系。這幅驚人的場景是由哈勃太空望遠鏡的影像數據構建而成，涵蓋了約半光年的範圍，位於赫比-哈羅 24 (HH 24)，距離地球約1300光年或400個秒差距，位於獵戶B分子雲複合體的恆星誕生區。HH 24的中央原恆星被冷卻的灰塵和氣體包圍，這些材料形成了一個旋轉的吸積盤。隨著吸積盤的材料向小恆星物體下降，它們會加熱。沿著系統的旋轉軸，對稱的噴流會被噴射出來。穿過該區域的星際物質，狹窄而充滿能量的噴流在它們的路徑上產生了一系列閃亮的衝擊前緣。
