螺旋星系 M 106 的中心發生了什麼?M 106 是一個由恆星和氣體組成的漩渦盤,它的外觀主要由藍色旋臂和靠近星系核的紅色塵埃通道組成,如圖所示,這些塵埃通道來自科威特沙漠。 M 106 的核心在無線電波和 X 射線中發出耀眼的光芒,在這裡發現了貫穿整個星系的雙噴流。 不尋常的中央發光使得M 106 成為最接近賽弗類星系的例子之一,在賽弗類星系中,大量發光氣體被認為正在落入一箇中央大質量黑洞。 M 106 也被命名為NGC 4258 ,距離我們比較近,有 2350 萬光年,橫跨 6 萬光年,用小型望遠鏡可以看到獵犬座(Canes Venatici)的方向。
原文:What's happening at the center of spiral galaxy M106? A swirling disk of stars and gas, M106's appearance is dominated by blue spiral arms and red dust lanes near the nucleus, as shown in the featured image taken from the Kuwaiti desert. The core of M106 glows brightly in radio waves and X-rays where twin jets have been found running the length of the galaxy. An unusual central glow makes M106 one of the closest examples of the Seyfert class of galaxies, where vast amounts of glowing gas are thought to be falling into a central massive black hole. M106, also designated NGC 4258, is a relatively close 23.5 million light years away, spans 60 thousand light years across, and can be seen with a small telescope towards the constellation of the Hunting Dogs (Canes Venatici).
