This cosmic pillar of gas and dust is nearly two light-years wide. The structure lies within one of our galaxy’s largest star forming regions, the Carina Nebula, shining in southern skies at a distance of about 7,500 light-years. The pillar’s convoluted outlines are shaped by the winds and radiation of Carina’s young, hot, massive stars. But the interior of the cosmic pillar itself is home to stars in the process of formation. In fact, a penetrating infrared view shows the pillar is dominated by two, narrow, energetic jets blasting outward from a still hidden infant star. The above featured visible light image was made in 2009 using the Hubble Space Telescope’s Wide Field Camera 3.

這個宇宙柱由氣體和塵埃組成，寬度接近兩光年。這一結構位於我們銀河系內最大的恆星形成區之一——Carina Nebula（獅子座星雲），距離約7,500光年。在Carina的年輕、炙熱的巨大恆星的風和輻射的影響下，這個柱子的錯綜複雜的輪廓被塑造出來。然而，這個宇宙柱的內部卻是恆星形成的活躍場所。事實上，穿透紅外線的觀測顯示，這根柱子內部有兩股狹窄的能量噴流，正朝著外界噴射，這些噴流來自尚未顯露的嬰兒恆星。上述的可見光影像是2009年使用Hubble Space Telescope的Wide Field Camera 3拍攝的。
