M104是一个华丽的旋涡星系，它以其接近边缘的轮廓而闻名，其特征是一圈模糊的尘埃带。这片由宇宙尘埃组成的狭长地带映衬着一大片中央恒星的轮廓，使星系看起来像一顶宽边的帽子，这让人联想到一个更受欢迎的绰号——草帽星系。这张著名星系的清晰光学图像是由地面图像数据制作而成，经过处理，保留了在M104明亮中央凸起的压倒性强光中经常丢失的细节。草帽星系也被称为NGC 4594，可以在整个光谱中看到，它是中心超大质量黑洞的宿主。M104直径约5万光年，距离我们2800万光年，是室女座星系团南部边缘最大的星系之一。尽管如此，这张视野中的彩色尖尖前景恒星仍然位于我们自己的银河系内。

A gorgeous spiral galaxy, M104 is famous for its nearly edge-on profile featuring a broad ring of obscuring dust lanes. Seen in silhouette against an extensive central bulge of stars, the swath of cosmic dust lends a broad brimmed hat-like appearance to the galaxy suggesting a more popular moniker, the Sombrero Galaxy. This sharp optical view of the well-known galaxy made from ground-based image data was processed to preserve details often lost in overwhelming glare of M104's bright central bulge. Also known as NGC 4594, the Sombrero galaxy can be seen across the spectrum, and is host to a central supermassive black hole. About 50,000 light-years across and 28 million light-years away, M104 is one of the largest galaxies at the southern edge of the Virgo Galaxy Cluster. Still the colorful spiky foreground stars in this field of view lie well within our own Milky Way galaxy.
