dust lane

dust lane

A belt of gas and dust that completely obscures the optical light from the center of an elliptical or S0 galaxy, forming a prominent dark band. Examples occur in Centaurus A and the Blackeye galaxy. Dust lanes are seen in edge-on spiral systems caused by obscuring matter in the galactic disk, as in the Sombrero galaxy.
