Centaurus A, An Elliptical Galaxy


Centaurus A (or Cen A for short) is a typical elliptical galaxy. Its unusual name comes from radio astronomy; Centaurus A was the first source of radio waves found in the constellation Centaurus.

This visible light picture shows a dark band running around the perimeter of Cen A. Astronomers believe this is a belt of dust around the galaxy which blocks light from the portions of Cen A behind it.
