Galaxies
Galaxies are the other islands in the universe beyond our own Milky Way. They are classified in three main groups; spirals (S), ellipticals (E) and irregulars (I). The spirals are divided in two groups; normal spirals (S) and barred spirals (SB).
A further classification is done with three small letters (a, b or c) behind the capital letters "S" or "SB", meaning : 'a' has tightly wound arms, 'b' has moderately wound arms and 'c' has loosely wound arms. The ellipticals display no spiral structure but are simply spheroidal or elliptical and are classified from perfectly round (E0) to elongated lens shaped (E7). Irregular galaxies are systems which appear as coarse masses of star clouds, lacking any symmetry or smooth star distribution.
