12. Kyle Willett - Univ. of Minnesota Zoo Workshop 2 - Apr 2013 7 Is the galaxy simply smooth and rounded, with no sign of a disk? Could this be a disk viewed edge-on? Is there a sign of a bar feature through the centre of the galaxy? Is there any sign of a spiral arm pattern? Is there anything odd? How many spiral arms are there? How prominent is the central bulge, compared to the rest of the galaxy? How tightly wound do the spiral arms appear? Does the galaxy have a bulge at its centre? If so, what shape? How rounded is it? Is the odd feature a ring, or is the galaxy disturbed or irregular?
