Why does the Sombrero Galaxy look like a hat? Reasons include the Sombrero’s unusually large and extended central bulge of stars, and dark prominent dust lanes that appear in a disk that we see nearly edge-on. Billions of old stars cause the diffuse glow of the extended central bulge. Close inspection of the bulge in the above photograph shows many points of light that are actually globular clusters. M104’s spectacular dust rings harbor many younger and brighter stars, and show intricate details astronomers don’t yet fully understand. The very center of the Sombrero glows across the electromagnetic spectrum, and is thought to house a large black hole. Fifty million-year-old light from the Sombrero Galaxy can be seen with a small telescope towards the constellation of Virgo. Follow APOD on: Facebook, Google Plus, or Twitter

為什麼 sombrero galaxy （帽子星系）看起來像一頂帽子？原因包括 sombrero 擁有不尋常的大型和延伸的中央星系，還有在幾乎邊緣可見的盤面上出現的深色明顯塵埃帶。數十億顆老星星造成了擴展中央星系的柔和光輝。仔細檢查上面照片中的中央星系，可以看到許多光點實際上是球狀星團。M104 的壯觀塵埃環中有許多年輕和更明亮的星星，顯示出天文學家尚未完全理解的複雜細節。帽子星系的中心散發著跨電磁波譜的光輝，据信那裡有一個大型黑洞。來自 sombrero galaxy 的五千萬年光芒可以用小型望遠鏡在處女座找到。
