Galactic Evolution
Galactic evolution refers to the process by which galaxies form, change, and develop over time. It begins with clouds of gas and dust in the universe, which collapse under gravity to create stars. These stars cluster together to form galaxies, which can evolve through interactions like mergers with other galaxies. Over billions of years, galaxies can change shape, form new stars, and even lose or gain mass. This evolution is influenced by their environment, dark matter, and the overall expansion of the universe. Understanding galactic evolution helps us learn about the history and future of the cosmos.
