Stellar Galaxies
Stellar galaxies are vast collections of stars, gas, dust, and dark matter bound together by gravity. They come in various shapes like spirals, ellipticals, and irregular forms, containing billions to trillions of stars. Galaxies are the fundamental building blocks of the universe, where star formation and cosmic evolution occur. They can be isolated or part of larger groups and clusters, interacting and evolving over billions of years. Understanding galaxies helps us learn about the origins and development of the universe, including how stars, planets, and possibly life, come into existence within these majestic cosmic structures.
