Dust Ring
As noted above, this galaxy's most striking feature is the dust lane that crosses in front of the bulge of the galaxy. This dust lane is actually a symmetric ring that encloses the bulge of the galaxy. Most of the cold atomic hydrogen gas and the dust lies within this ring. The ring might also contain most of the Sombrero Galaxy's cold molecular gas, although this is an inference based on observations with low resolution and weak detections. Additional observations are needed to confirm that the Sombrero galaxy's molecular gas is constrained to the ring. Based on infrared spectroscopy, the dust ring is the primary site of star formation within this galaxy.

Famous quotes containing the words dust and/or ring:
“Sometimes Death, puffing at the doore,
Blows all the dust about the floore:
But while he thinks to spoil the room, he sweeps.
Blest be the Architect, whose art
Could build so strong in a weak heart.”
—George Herbert (1593–1633)
“These words dropped into my childish mind as if you should accidentally drop a ring into a deep well. I did not think of them much at the time, but there came a day in my life when the ring was fished up out of the well, good as new.”
—Harriet Beecher Stowe (1811–1896)
