在这个螺旋星系的中心有一个螺旋星系吗？排序的。来自哈勃太空望远镜、欧洲南方天文台和地球上的小型望远镜的图像数据结合在一起，形成了这幅正面的螺旋星系梅西耶61 （M61）及其明亮中心的详细肖像。M61也被称为NGC 4303，距离室女座星系团仅5500万光年。它被认为是棒旋星系的一个例子，类似于我们的银河系。像其他的螺旋星系一样，M61也有广阔的旋臂、宇宙尘埃带、粉红色的恒星形成区和年轻的蓝色星团。它的核心有一个活跃的超大质量黑洞，周围环绕着一个明亮的核螺旋——流入的恒星形成气体，它本身看起来就像一个独立的螺旋星系。APOD满30岁了！：今晚（星期二）晚上7点在爱尔兰科克市举行免费公开讲座

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.
