WebThe arms of a spiral galaxy have lots of gas and dust, and they are often areas where new stars are constantly forming. The bulge of a spiral galaxy is composed primarily of old, red stars. Very little star formation goes on in the bulge. The table below shows the abbreviations that are used for spiral galaxy types. WebStandard spiral galaxies are given the symbol S. At least half of spirals seem to have a bar structure in the middle, and these are given the symbol SB. Spirals are given another letter which is based on how tight the spiral arms are, and how big the central bulge is. Sa (and SBa) galaxy types have tightly wound arms and large central bulges.
