Galaxy Evolution
Galaxy evolution refers to the changes that galaxies undergo over time. Initially, galaxies form from clouds of gas and dust, which collapse under gravity. They grow through processes like merging with other galaxies and forming new stars. Over billions of years, their structure changes from irregular shapes to more organized spirals or ellipticals. Factors like dark matter, supernovae, and supermassive black holes influence this evolution. Studying galaxy evolution helps us understand the history of the universe, the formation of stars, and the role of galaxies in cosmic development.
