The three main types of galaxies are spiral, elliptical, and irregular galaxies. Spiral galaxies, like the Milky Way, have a rotating disk with arms that curl outward, containing stars, gas, and dust. Elliptical galaxies are more rounded and lack the distinct features of spiral arms, often older and with less interstellar material. Irregular galaxies do not have a defined shape, often appearing chaotic. Earth is part of the Milky Way galaxy, which is classified as a spiral galaxy.
