NGC 6072: A Complex Planetary Nebula from Webb

Explanation: Why is this nebula so complex? The Webb Space Telescope has imaged a nebula in great detail that is thought to have emerged from a Sun-like star. NGC 6072 has been resolved into one of the more unusual and complex examples of planetary nebula. The featured image is in infrared light with the red color highlighting cool hydrogen gas. Study of previous images of NGC 6072 indicated several likely outflows and two disks inside the jumbled gas, while the new Webb image resolves new features likely including one disk’s edge protruding on the central left. A leading origin hypothesis holds that the nebula’s complexity is caused or enhanced by multiple outbursts from a star in a multi-star system near the center.

NGC 6072: 来自韦伯望远镜的复杂行星状星云

说明: 为什么这个星云如此复杂？韦伯太空望远镜拍摄了一个星云的详细影像，这个星云被认为是由类似太阳的恒星演化而来的，而它的形状NGC 6072咸认是行星状星云中较为不寻常且复杂的范例之一。这幅主题影像是摄于红外光波段，红色用以突显低温的氢气体。先前NGC 6072影像的研究显示，星云中可能存在多个外泛喷流和两个盘状结构，而新的韦伯影像解析出新的特征，可能包括一个盘的边缘突出于中央左侧。一个主要的起源假说认为，星云的复杂性是由于位于中心附近的多星系统中的恒星多次爆发所引起或强化。
