[漢羅] 行星形星雲 Mz3：狗蟻星雲

這隻狗蟻敢毋是一个大球體？ 行星形星雲 Mz3 是一个去予像咱 太陽 仝款 ê 恆星 kā 擲–出去 ê 物質，所以一定是圓–ê。 毋閣，是按怎這个 噴–出去 ê 氣體生做 狗蟻形，毋是圓 ê？ 這个線索可能會當 tī 這个去予用一秒鐘 1000 公里緊 ê 速度噴–出去 ê 氣體，這个 光年 長 ê 結構，閣有這个星雲中心 恆星 ê 磁性 內底揣著。 另外一个可能 ê 答案，是 Mz3 閣藏一粒較暗 ê 恆星，踅 較光彼粒 leh 行。 有一个可能性較懸 ê 假設 講，是中心恆星 ê 自旋 kah 磁場 leh 引導氣體。 因為這个中心恆星 敢若 kah 咱 ê 太陽足仝 ê，天文學家 希望會當 閣較了解 這隻大隻太空 狗蟻 ê 歷史。 按呢 to̍h 會當提供有路用 ê 見識，予咱了解咱 ê 太陽 kah 地球 ê 未來。

[English] Planetary Nebula Mz3: The Ant Nebula

Why isn’t this ant a big sphere? Planetary nebula Mz3 is being cast off by a star similar to our Sun that is, surely, round. Why then would the gas that is streaming away create an ant-shaped nebula that is distinctly not round? Clues might include the high 1000-kilometer per second speed of the expelled gas, the light-year long length of the structure, and the magnetism of the star featured here at the nebula’s center. One possible answer is that Mz3 is hiding a second, dimmer star that orbits close in to the bright star. A competing hypothesis holdshypothesis holds that the central star’s own spin and magnetic field are channeling the gas. Since the central star appears to be so similar to our own Sun, astronomers hope that increased understanding of the history of this giant space ant can provide useful insight into the likely future of our own Sun and Earth.
