IRAS 04302 :蝴蝶盤行星形成
IRAS 04302: Butterfly Disk Planet Formation

發表日期:2025-09-08
這隻蝴蝶能孵化行星從恆星IRAS 04302 + 2247 上扇形展開的星雲可能看起來像蝴蝶的翅膀,而中間垂直的棕色條紋可能看起來像蝴蝶的身體--但它們共同表明這是一個活躍的行星形成系統。這張照片是韋伯太空望遠鏡(Webb Space Telescope)最近用紅外線拍攝的。圖中,垂直圓盤上有厚厚的氣體和塵埃,行星就是從這些氣體和塵埃中形成的。這個圓盤遮擋了來自中心恆星的可見光和(大部分)紅外光,從而可以很好地觀察到周圍反射光的塵埃。在接下來的幾百萬年裡,塵埃盤可能會在新孵化行星的引力作用下碎裂成環。 十億年後,剩餘的氣體和塵埃可能會消散,主要留下行星--就像我們的太陽系一樣。 探索宇宙隨機 APOD 生成器
原文: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
