原文:
This floating ring is the size of a galaxy. In fact, it is a galaxy — or at least part of one: the photogenic Sombrero Galaxy, one of the largest galaxies in the nearby Virgo Cluster of Galaxies. The dark band of dust that obscures the mid-section of the Sombrero Galaxy in optical light actually glows brightly in infrared light. The above image, digitally sharpened, shows the infrared glow, recently recorded by the orbiting Spitzer Space Telescope, superposed in false-color on an existing image taken by NASA’s Hubble Space Telescope in optical light. The Sombrero Galaxy, also known as M104, spans about 50,000 light years across and lies 28 million light years away. M104 can be seen with a small telescope in the direction of the constellation Virgo.

這個浮動的環大小如同一個星系,事實上,它正是星系的一部分:其光彩奪目的索姆布雷羅星系(Sombrero Galaxy),是鄰近的處女座星系團(Virgo Cluster of Galaxies)中最大的星系之一。遮住索姆布雷羅星系中段的黑暗塵埃帶,在紅外線光下卻閃耀著明亮的光芒。上面的圖片是透過環繞地球運行的斯皮策太空望遠鏡(Spitzer Space Telescope)最近錄得的紅外線光輻射,並以假色彩重疊在由美國宇航局哈勃太空望遠鏡(Hubble Space Telescope)拍攝的光學影像上。索姆布雷羅星系,也稱為M104,寬約50,000光年,距離我們約2800萬光年。用小望遠鏡可以在處女座(Virgo)星座的方向觀賞到M104。
