[漢羅] 貓眼星雲 ê 中心

Tī 3000 光年遠 ê 所在，有一粒欲死–去 ê 恆星 kā 伊 ê 發光氣體殼擲出去。 這張相片 是 Hubble 太空望遠鏡 翕 ê 貓眼星雲 (NGC 6543)，是目前咱知影 ê 行星形星雲 內底 上複雜–ê。 這張 貓眼星雲 相片實在是有夠複雜–ê，伊有半 光年 闊。 天文學家懷疑講，tī 伊 中心 ê 天體，可能是一組 雙星系統。 這款形體 ê 天體攏叫做「行星形星雲」，毋閣會按呢號名，其實是一个 誤會。 雖然講這款天體 tī 細台天文望遠鏡內底看起來是圓–ê，kah 行星欲仝欲仝。 毋閣咱若是用懸解析度 ê 大型天文望遠鏡 kā 看，就會看著恆星外圍有一个 恆星繭，這是 恆星演化 到上尾坎站 ê 時陣，去予歕出去 ê 氣體殼。 天文學家若是 tùi 貓眼星雲硞硞 kā 看，毋若會看著閣較清楚 ê 結構，嘛會看著太陽閣 50 億年，仝款會演化到 行星形星雲 ê 階段。

[English] In the Center of the Cat’s Eye Nebula

Three thousand light-years away, a dying star throws off shells of glowing gas. This image from the Hubble Space Telescope reveals the Cat’s Eye Nebula (NGC 6543), to be one of the most complex planetary nebulae known. Spanning half a light-year, the features seen in the Cat’s Eye are so complex that astronomers suspect the bright central object may actually be a binary star system. The term planetary nebula, used to describe this general class of objects, is misleading. Although these objects may appear round and planet-like in small telescopes, high resolution images with large telescopes reveal them to be stars surrounded by cocoons of gas blown off in the late stages of stellar evolution. Gazing into this Cat’s Eye, astronomers may well be seeing more than detailed structure, they may be seeing the fate of our Sun, destined to enter its own planetary nebula phase of evolution … in about 5 billion years.
