这种蝴蝶能孵化行星。从恒星IRAS 04302+2247展开的星云可能看起来像蝴蝶的翅膀，而中心向下的垂直棕色条纹可能看起来像蝴蝶的身体——但它们一起表明了一个活跃的行星形成系统。这张特色图片是最近由韦伯太空望远镜用红外光拍摄的。如图所示，垂直圆盘上布满了形成行星的气体和尘埃。这个圆盘遮挡了来自中央恒星的可见光和（大部分）红外光，使人们能够很好地观察周围反射出光线的尘埃。在接下来的几百万年里，尘埃盘很可能会在新孵化的行星的引力作用下分裂成环。10亿年后，剩余的气体和尘埃可能会消散，留下主要的行星——就像我们的太阳系一样。探索宇宙：随机APOD生成器

This butterfly can hatch planets. The nebula fanning out from the star IRAS 04302+2247 may look like the wings of a butterfly, while the vertical brown stripe down the center may look like the butterfly's body -- but together they indicate an active planet-forming system. The featured picture was captured recently in infrared light by the Webb Space Telescope. Pictured, the vertical disk is thick with the gas and dust from which planets form. The disk shades visible and (most) infrared light from the central star, allowing a good view of the surrounding dust that reflects out light. In the next few million years, the dust disk will likely fragment into rings through the gravity of newly hatched planets. And a billion years from now, the remaining gas and dust will likely dissipate, leaving mainly the planets -- like in our Solar System. Explore the Universe: Random APOD Generator
