Detailed explanation-1: -There are three general types: elliptical, spiral, and irregular. Perhaps the most familiar kind of galaxy are spiral galaxies. They have a distinctive shape with spiral arms in a relatively flat disk and a central “bulge". The bulge has a large concentration of stars.
Detailed explanation-2: -The smallest of galaxies contain a “mere” few hundred million stars while the largest galaxies contain up to one hundred trillion stars! Scientists have been able to segment galaxies into 4 main types: spiral, elliptical, peculiar, and irregular.
Detailed explanation-3: -Spiral galaxies have spiraling arms extending from their centers, giving them a pinwheel appearance. Elliptical galaxies range in how nearly spherical they appear from E0 to E7. Irregular galaxies lack a distinct shape altogether. 01-Oct-2021
