M 83 lies pretty far south for N. American and most European observatories to do it justice. This image from Chile shows much of the color and detail that this relatively nearby (4.5 Mpc) spiral galaxy offers.

It is a “grand design” spiral galaxy. “Grand design” means that it has distinct spiral arms extending for a large angular distance around the galaxy and discernable over much of its radius. In addition to the spiral arms, M 83 has a weakly expressed bar but no inner ring.
