[漢羅] NGC 2440：新 ê 白矮星 ê 繭

中央彼是啥物？是白矮星！ 白矮星 kah 尾蝶仔 仝款，會 kā 共家己包起來 ê 繭，就是氣體殼，擲出去，開始一个新 ê 性命週期。 照這个比喻，咱 ê 日頭 是 刺毛蟲，去予擲出去 ê 氣體殼就是 上媠 ê 繭。 這張相片內底 ê 繭，是 編號 NGC 2440 ê 行星形星雲，內底有到目前為止 溫度上懸 ê 白矮星。 白矮星 就是相片中央附近彼个柑仔色 ê 光點。 咱 ê 太陽 免 50 億年，嘛會變做一隻「白矮星 尾蝶仔」。

[English] NGC 2440: Cocoon of a New White Dwarf

What’s that in the center? Like a butterfly, a white dwarf star begins its life by casting off a cocoon of gas that enclosed its former self. In this analogy, however, the Sun would be a caterpillar and the ejected shell of gas would become the prettiest cocoon of all. In the featured cocoon, the planetary nebula designated NGC 2440 contains one of the hottest white dwarf stars known. The white dwarf can be seen as the bright orange dot near the image center. Our Sun will eventually become a white dwarf butterfly, but not for another 5 billion years.
