從可見光到 X 射線的蟹狀星雲
The Crab Nebula from Visible to X-Ray

發表日期:2024-07-23
蟹狀星雲的動力是什麼?一顆城市大小的磁中子星,每秒旋轉約 30 次。它被稱為蟹狀脈衝星,是星雲核心氣體漩渦中心的亮點。 蟹狀星雲(M 1 )的壯觀畫面寬約 10 光年,畫面上有一個漩渦狀的中心圓盤,以及由周圍不斷膨脹的發光氣體組成的複雜細絲。圖片中紅色和藍色為哈勃太空望遠鏡發出的可見光,白色為錢德拉 X 射線天文臺發出的 X 射線光,紫色為漫反射 X 射線偏振探測儀(IXPE)探測到的漫反射 X 射線。 中央脈衝星透過略微減慢其自旋速率來驅動高能電子風,從而為蟹狀星雲的發射和膨脹提供動力。 今天是 NASA 旗艦級 X 射線天文臺發射 25 週年紀念日,釋出的專題圖片:錢德拉。 眾多發現:錢德拉天文臺 25 週年慶典
原文: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. Many Discoveries: Chandra Celebrates 25th Anniversary
