[漢羅] 變色杜定暗星雲

有當時仔星際空間內底 ê 暗塗粉 特殊 ê 形態實在是足優雅 ê。 比論講上南爿 ê 變色杜定座 就是按呢。 咱知影講暗塗粉會 kā 後壁 ê 恆星 抑是 星雲 ê 可見光閘著，所以 in 平常時是 傷暗看無。 毋閣 這張 4 點鐘久 ê 感光 內底，大部份看著 ê 是 塗粉 家己 ê 光，咖啡色色調是伊較強 ê 紅光 kah 近紅外線 ê 部份。 Tī 中央正爿有一粒較藍較光 ê 恆星，是 變色杜定座 β 星。 伊本底就是一粒發藍白光 ê 恆星，伊邊仔 ê 塗粉 to̍h 拄仔好反射伊 ê 藍光。 相片內底 ê 恆星 kah 塗粉 攏是 tī 咱銀河系內底。 毋閣有一个較明顯 ê 例外：Tī 變色杜定座 β 星下底 ê 白色光點 是 tī 遠方 ê IC 3104 星系。 星際塗粉 大部份是 tī 巨恆星 較冷 ê 大氣層內底產生，才去予恆星光、恆星風、抑是 恆星爆炸（比論講 超新星）kā 捒出去 ê。

[English] Chamaeleon Dark Nebulas

Sometimes the dark dust of interstellar space has an angular elegance. Such is the case toward the far-south constellation of Chamaeleon. Normally too faint to see, dark dust is best known for blocking visible light from stars and galaxies behind it. In this four-hour exposure, however, the dust is seen mostly in light of its own, with its strong red and near-infrared colors giving creating a brown hue. Contrastingly blue, the bright star Beta Chamaeleontis is visible just to the right of center, with the dust that surrounds it preferentially reflecting blue light from its primarily blue-white color. All of the pictured stars and dust occur in our own Milky Way Galaxy with – but one notable exception: the white spot just below Beta Chamaeleontis is the galaxy IC 3104 which lies far in the distance. Interstellar dust is mostly created in the cool atmospheres of giant stars and dispersed into space by stellar light, stellar winds, and stellar explosions such as supernovas.
