[漢羅] 貓眼星雲 ê 雲暈

是啥物 tī 貓眼星雲邊仔產生這个無四常 ê 雲暈？無人知影。 咱知影 ê 是，貓眼星雲 (NGC 6543) 是天頂上出名 ê 行星形星雲 之一。 雖罔講相片 中央 彼个足光 ê 對伨結構 hŏng 印象足深 ê，毋閣這張相片主要是欲予逐家看伊 ê 外層雲暈，這差不多有 3 光年 闊。 行星形星雲 以早去 hŏng 認為講，伊是像太陽這款恆星行到 性命 上尾 ê 坎站。 毋閣最近有揣著一寡行星形星雲有 脹大 ê 雲暈，這可能是 咱猶毋是蓋清楚 ê 恆星演化 早期，拄 kā 邊仔 ê 物質褪掉 ê 款。 是講 行星形星雲這个階段，去 hŏng 認為講 會擋 1 萬年左右。 天文學家估計講，貓眼星雲 雲暈 ê 外層雲絲彼部份，可能有 5 萬到 9 萬歲。

[English] Halo of the Cat's Eye

What created the unusual halo around the Cat's Eye nebula? No one is sure. What is sure is that the Cat's Eye Nebula (NGC 6543) is one of the best known planetary nebulae on the sky. Although haunting symmetries are seen in the bright central region, this image was taken to feature its intricately structured outer halo, which spans over three light-years across. Planetary nebulae have long been appreciated as a final phase in the life of a Sun-like star. Only recently however, have some planetaries been found to have expansive halos, likely formed from material shrugged off during earlier puzzling episodes in the star's evolution. While the planetary nebula phase is thought to last for around 10,000 years, astronomers estimate the age of the outer filamentary portions of the Cat's Eye Nebula's halo to be 50,000 to 90,000 years.
