[漢羅] 超新星殘骸 Simeis 147

這張是 超新星殘骸 Simeis 147 ê 細節影像，看會著面頂有複雜 ê、規虯 ê、扭曲 ê 雲絲。 你若是綴面頂 ê 線路行，按呢你可能會揣無路。 伊嘛予編做 Sharpless 2-240，猶閣有另外一个較有名 ê 名是意大利麵星雲。 你若是 ùi 金牛座 kah 御夫座 ê 邊界 看過去，to̍h 知影伊 tī 天頂 ê 視野是 3 度闊，差不多是 6 粒月娘 ê 大細。 若是用伊 ê 距離 3000 光年來推算，這个恆星屑仔雲差不多是 150 光年大。 這張相片是 ùi 狹頻濾鏡 提著 ê 影像資料 kā 組合起來 ê。 內底較紅 ê 發射線是 ùi 去予離子化 ê 水素原子，較暗 ê 青藍色是 雙離子化 ê 酸素原子。 In 是 leh 追蹤 受著衝擊 ê 發光氣體。 超新星殘骸進前估算 ê 距離差不多是 4 萬年，意思是講這粒大質量恆星爆炸了後，上早發出 ê 光 行到地球已經是 4 萬年前 ê 代誌矣。 毋閣這个脹大 ê 殘骸毋是唯一 ê 產物。 這个宇宙災難 閣有留 一粒自旋 ê 中子星 抑是 脈動星 落來。 毋管是留佗一款，攏是 ùi 原底彼粒恆星 ê 核心來 ê。

[English] Supernova Remnant Simeis 147

It's easy to get lost following the intricate, looping, twisting filaments in this detailed image of supernova remnant Simeis 147. Also cataloged as Sharpless 2-240 it goes by the popular nickname, the Spaghetti Nebula. Seen toward the boundary of the constellations Taurus and Auriga, it covers nearly 3 degrees or 6 full moons on the sky. That's about 150 light-years at the stellar debris cloud's estimated distance of 3,000 light-years. This composite includes image data taken through narrow-band filters where reddish emission from ionized hydrogen atoms and doubly ionized oxygen atoms in faint blue-green hues trace the shocked, glowing gas. The supernova remnant has an estimated age of about 40,000 years, meaning light from the massive stellar explosion first reached Earth 40,000 years ago. But the expanding remnant is not the only aftermath. The cosmic catastrophe also left behind a spinning neutron star or pulsar, all that remains of the original star's core.
