Explanation: To some, it may look like a beehive. In reality, the featured image from the Hubble Space Telescope captures a cosmic pillar of dust, over two-light years long, inside of which is Herbig-Haro 666 — a young star emitting powerful jets. 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 layered outline are shaped by the winds and radiation of Carina’s young, hot, massive stars, some of which are still forming inside the nebula. A dust-penetrating view in infrared light better shows the two, narrow, energetic jets blasting outward from a still hidden infant star.

说明: 有人认为这个天体形似蜂巢。其实，这张由哈勃太空望远镜拍摄的主题影像，呈现的是一道长达2光年的宇宙尘埃柱，其内的一颗年轻恒星喷出了强大的喷流，激发出赫比格-哈罗天体666 (HH 666)。这个结构体位在我们银河系最大恒星形成区船底大星云之内，远在南天7,500光年之处绽放辉光。这道尘埃柱的层状轮廓，是受到船底座众多的炽热年轻大质量恒星的恒星风和辐射之塑形，而位在星云内的部分恒星，仍处于形成阶段。在能够透视尘埃的红外光段进行观测，可清楚见到二道狭窄的强大喷流，从一颗仍然隐藏的恒星喷出。
