中文翻譯:
在宇宙的深處，有一個叫做Messier 61的星系。這個星系就像是一個大漩渦，裡面有很多閃亮的星星在轉動。它離我們有55萬光年之遠，住在一個叫做Virgo星團的地方。Messier 61是一個橫桿螺旋星系，樣子跟我們的銀河系很相似。在這個星系裡，你可以看到美麗的螺旋臂，還有一個明亮的中央，裡面有一個非常大的黑洞。這個黑洞正在吃著附近的氣體，形成了一個像漩渦一樣的場景。想像一下，如果你在那裡，肯定會覺得十分神奇！
原文:
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.
