[漢羅] 毛蟹星雲內底 咧 自旋 ê 脈動星

毛蟹星雲 ê 核心有一粒 kah 城市平大、有磁性 ê 中子星，伊一秒鐘會自旋 30 擺。 伊就叫做 毛蟹星雲脈動星，是 tī 星雲核心 這寡咧轉踅氣體 ê 中央 上光彼點。 毛蟹星雲 中心彼搭 ê 發光氣體、閬空、kah 捲踅 ê 雲絲，實在是足壯觀--ê，這差不多有 12 光年闊。 這張相片 是 kā 三个波段 ê 影像疊做一張--ê。 Hubble 太空望遠鏡 ê 可見光 是茄仔色--ê，Chandra X-光太空天文台 ê X-光 是藍色--ê，Spitzer 太空望遠鏡 ê 紅外線 是紅色--ê。 毛蟹星雲脈動星就親像是一台 宇宙發電機 仝款，伊會 予毛蟹星雲動力 產生發射線，ùi 四箍圍仔 ê 物質驅動 震波，kā 轉踅 ê 電子加速。 這粒 會自旋 ê 脈動星，是大質量恆星 爆炸 了後崩塌 ê 核心。 伊 ê 質量比 太陽 較大，毋閣伊 ê 密度 kah 原子核 仝款。 毛蟹星雲脈動星 ê 外層，是做恆星 ê 氣體脹大 ê 殘骸。 是講，地球人 tī 1054 年 ê 時陣，就捌看過 超新星爆炸矣。

[English] The Spinning Pulsar of the Crab Nebula

At the core of the Crab Nebula lies a city-sized, magnetized neutron star spinning 30 times a second. Known as the Crab Pulsar, it is the bright spot in the center of the gaseous swirl at the nebula's core. About twelve light-years across, the spectacular picture frames the glowing gas, cavities and swirling filaments near the Crab Nebula's center. The featured picture combines visible light from the Hubble Space Telescope in purple, X-ray light from the Chandra X-ray Observatory in blue, and infrared light from the Spitzer Space Telescope in red. Like a cosmic dynamo the Crab pulsar powers the emission from the nebula, driving a shock wave through surrounding material and accelerating the spiraling electrons. With more mass than the Sun and the density of an atomic nucleus,the spinning pulsar is the collapsed core of a massive star that exploded. The outer parts of the Crab Nebula are the expanding remnants of the star's component gasses. The supernova explosion was witnessed on planet Earth in the year 1054.
