在宇宙的遙遠角落,有一個叫做M61的漂亮星系,距離我們約有5500萬光年遠。它是一個像我們的銀河系一樣的螺旋星系,也有著一點特別的地方,它的中心有個活躍的超大質量黑洞。在M61的周圍,我們可以看到美麗的螺旋臂、五彩的星雲和年輕的藍色星團,這裡的星星正在快速地形成。不過最神奇的是,星系的中心就像一個小螺旋星系,包圍著明亮的核螺旋,有許多星星正在向內匯聚,形成新的星星。真是個神秘而美麗的地方!

Is there a spiral galaxy in the center of this spiral galaxy? Sort of. Image data from the Hubble Space Telescope, the European Southern Observatory, and smaller telescopes on planet Earth are combined in this detailed portrait of face-on spiral galaxy Messier 61 (M61) and its bright center. A mere 55 million light-years away in the Virgo Cluster of Galaxies, M61 is also known as NGC 4303. It’s considered to be an example of a barred spiral galaxy similar to our own Milky Way. Like other spiral galaxies, M61 also features sweeping spiral arms, cosmic dust lanes, pinkish star forming regions, and young blue star clusters. Its core houses an active supermassive black hole surrounded by a bright nuclear spiral — infalling star-forming gas that itself looks like a separate spiral galaxy.
