[漢羅] Ùi 可見光 到 X 光 ê 毛蟹星雲
毛蟹星雲 ê 動力來源是啥物? 是一粒大細差不多 kah 城市平大,1 秒鐘 自旋 30 擺、有磁性 ê 中子星。 伊嘛叫做 毛蟹星雲脈動星,是星雲核心 氣體捲螺仔旋中心 ê 光點。 毛蟹星雲 M1 差不多有 10 光年闊。 這張 壯麗 ê 相片 有翕著 捲螺仔旋 ê 中央盤 kah 踅 tī 邊仔、沓沓仔湠出去--ê、足複雜 ê 雲絲。 這張相片是 kā 紅色 ê Hubble 太空望遠鏡 ê 可見光 影像,白色 ê Chandra X 光天文台 ê X 光 影像,kah 茄仔色 ê IXPE 偏振探測器 ê X 光發射線 疊做伙 ê 合成相片。 中央 ê 脈動星 透過 沓沓仔 降低 自旋速度 ê 方式,驅動 毛蟹星雲 產生發射線 kah 脹大,產生 高能 電子 風。 這張 今仔日發表 ê 影像,是欲紀念 NASA 旗艦級 天文台:Chandra X 光天文台 發射 25 週年。

[English] The Crab Nebula from Visible to X-Ray
What powers the Crab Nebula? A city-sized magnetized neutron star spinning around 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 10 light-years across, the spectacular picture of the Crab Nebula (M1) frames a swirling central disk and complex filaments of surrounding and expanding glowing gas. The picture combines visible light from the Hubble Space Telescope in red and blue with X-ray light from the Chandra X-ray Observatory shown in white, and diffuse X-ray emission detected by Imaging X-ray Polarimetry Explorer (IXPE) in diffuse purple. The central pulsar powers the Crab Nebula's emission and expansion by slightly slowing its spin rate, which drives out a wind of energetic electrons. The featured image released today, the 25th Anniversary of the launch of NASA's flagship-class X-ray Observatory: Chandra.
