当一颗恒星的核燃料耗尽时会发生什么？对于像太阳这样的恒星，中心凝结成一颗白矮星，而外层的大气层被驱逐到太空中，形成行星状星云。行星状星云NGC 1514排出的外层大气在可见光下看起来是一团混乱的气泡。但詹姆斯·韦伯太空望远镜的红外线图像证实了一个不同的故事：在这个光线下，星云呈现出一个独特的沙漏形状，这被解释为沿对角线看到的圆柱体。如果你仔细观察星云的中心，你还可以看到一颗明亮的中央恒星，它是双星系统的一部分。更多的观测可能会更好地揭示这个星云是如何演变的，以及中心恒星是如何共同工作的，从而产生了我们观察到的有趣的圆柱体和气泡。跳跃宇宙：随机APOD生成器

What happens when a star runs out of nuclear fuel? For stars like our Sun, the center condenses into a white dwarf while the outer atmosphere is expelled into space to appear as a planetary nebula. The expelled outer atmosphere of planetary nebula NGC 1514 appears to be a jumble of bubbles -- when seen in visible light. But the view from the James Webb Space Telescope in infrared, as featured here, confirms a different story: in this light the nebula shows a distinct hourglass shape, which is interpreted as a cylinder seen along a diagonal. If you look closely at the center of the nebula, you can also see a bright central star that is part of a binary system. More observations might better reveal how this nebula is evolving and how the central stars are working together to produce the interesting cylinder and bubbles observed.
