M 77 :中心活躍的螺旋星系
M77: Spiral Galaxy with an Active Center

發表日期:2025-12-02
附近的螺旋星系 M 77 的中心發生了什麼?這個迎面而來的星系距離海怪星座(鯨魚座)僅有 4700 萬光年。 在這個估計距離上,這個絢麗的宇宙島大約有 10 萬光年寬。 它也被稱為 NGC 1068 ,其緊湊而明亮的核心被探索活動賽弗星系中超大質量黑洞奧秘的天文學家們研究得很透徹。 M 77 的活躍核心在 X 射線、紫外線、可見光、紅外線和射電波段都能發出耀眼的光芒。 這張 M 77 的清晰影像是由哈勃太空望遠鏡拍攝的。影像顯示了被紅色塵埃雲和藍色星團遮擋的螺旋旋臂的細節,所有這些都環繞著星系明亮的白色發光中心。 鳳凰城免費 APOD 講座: 12 月 10 日星期三晚上 7 點
原文:What's happening in the center of nearby spiral galaxy M77? The face-on galaxy lies a mere 47 million light-years away toward the constellation of the Sea Monster (Cetus). At that estimated distance, this gorgeous island universe is about 100 thousand light-years across. Also known as NGC 1068, its compact and very bright core is well studied by astronomers exploring the mysteries of supermassive black holes in active Seyfert galaxies. M77's active core glows bright at x-ray, ultraviolet, visible, infrared, and radio wavelengths. The featured sharp image of M77 was taken by the Hubble Space Telescope. The image shows details of the spiral's winding spiral arms as traced by obscuring red dust clouds and blue star clusters, all circling the galaxy's bright white luminous center.
