M 1 :不可思議的膨脹蟹
M1: The Incredible Expanding Crab

發表日期:2025-05-08
蟹狀星雲被編入M 1 星表,是查爾斯-梅西耶(Charles Messier)著名的非彗星列表中的第一個。事實上,蟹狀星雲現在已經知道是一顆超新星的殘餘物,是一顆大質量恆星死亡爆炸後不斷膨脹的碎片雲。天文學家在 1054 年目睹了蟹狀星雲的誕生。星雲的直徑約為 10 光年,目前仍在以每秒約 1500 公里的速度膨脹。透過對比哈勃太空望遠鏡和詹姆斯-韋伯太空望遠鏡拍攝的這些清晰影像,你可以看到星雲的擴張。哈勃在 2005 年用可見光捕捉到了蟹狀體充滿活力、支離破碎的細絲,韋伯在 2023 年用紅外光捕捉到了蟹狀體充滿活力、支離破碎的細絲。這種宇宙甲殼動物位於大約 6500 光年之外的金牛座。
原文:Cataloged as M1, the Crab Nebula is the first on Charles Messier's famous list of things which are not comets. In fact, the Crab Nebula is now known to be a supernova remnant, an expanding cloud of debris from the death explosion of a massive star. The violent birth of the Crab was witnessed by astronomers in the year 1054. Roughly 10 light-years across, the nebula is still expanding at a rate of about 1,500 kilometers per second. You can see the expansion by comparing these sharp images from the Hubble Space Telescope and James Webb Space Telescope. The Crab's dynamic, fragmented filaments were captured in visible light by Hubble in 2005 and Webb in infrared light in 2023. This cosmic crustacean lies about 6,500 light-years away in the constellation Taurus.
