What is Understanding Galaxy Types and Formation about?
Galaxies come in three main types - spiral, elliptical, and irregular. Spiral galaxies like the Milky Way contain stars, planets, dust and gas rotating around the galactic center in spiral arms. Elliptical galaxies are round but elongated shapes containing older stars. Irregular galaxies have misshapen forms often due to gravitational interactions. Galaxies interact and sometimes merge together, shaping the evolution of the universe over billions of years since its beginning.
