说明: 醒目的螺旋星系M104,是以它几乎侧向的宽广圈状黝黑尘埃带着称。而在鼓胀星系核心明亮恒星的衬托下,这道黝黑的宇宙尘埃带,让星系看似戴着宽边帽,因而让它博得草帽星系的雅号。上面这幅使用哈伯太空望远镜数据建构出影像,呈现了这个着名星系的清晰身影。这幅重新经过处理的影像,除了让星系拥有自然的色泽之外,也让以往使用较小型地面仪器观测此星系时,受到明亮核心眩目光芒淹没的细微结构得以显现出来。草帽星系亦名为NGC 4594,在所有电磁波段都得见,因此咸认它的核心藏有超大质量黑洞。 M104离我们约2千8百万光年远,大小则在5万光年左右,是室女座星系团南缘最大的星系之一。

Explanation: The striking spiral galaxyM104 is famousfor its nearly edge-onprofile featuring a broad ring of obscuring dust lanes.Seen in silhouette against an extensive central bulge of stars,the swath of cosmic dust lends abroad brimmed hat-like appearance to the galaxy suggestinga more popular moniker, The Sombrero Galaxy.Hubble Space Telescope data have been used tocreatethis sharpview of thewell-known galaxy.The processing results in a natural color appearanceand preserves details often lost in overwhelming glare of M104'sbright central bulge when viewed with smaller ground-basedtelescopes.Also known as NGC 4594, the Sombrero galaxy can be seenacross the spectrum andis host to a centralsupermassive black hole.About 50,000 light-years across and 28 million light-years away,M104 is one of thelargest galaxies at the southern edge of theVirgo Galaxy Cluster.
