Stellar observation is the practice of studying stars and other celestial bodies to understand their properties, behavior, and evolution. This can be done using telescopes, which collect light from distant objects, allowing astronomers to analyze their brightness, color, and distance. Observations can reveal important information about the life cycles of stars, including their formation, aging, and eventual death. Astronomers often focus on specific types of stars, such as red giants or neutron stars, to gather data that contributes to our knowledge of the universe. By observing patterns and changes in these celestial objects, scientists can develop theories about the Milky Way galaxy and the broader cosmos.
