Galaxies are large systems consisting of stars, planets, gas, dust, and other celestial objects, bound together by gravity. They come in various shapes and sizes, ranging from small dwarf galaxies with millions of stars to massive galaxies with trillions of stars. Some of the most common types of galaxies include spiral galaxies like our Milky Way, elliptical galaxies that are more spheroidal in shape, and irregular galaxies with irregular shapes and structures.
