Astrophysics

Astrophysics explores the physical properties and behaviors of matter and energy in the universe, from stars and galaxies to black holes and cosmic backgrounds. Unlike general physics, it specifically addresses astronomical phenomena, integrating principles of mechanics, thermodynamics, quantum theory, and relativity to interpret how the cosmos functions and evolves.

Readers interested in astrophysics can focus on subfields such as stellar structure, cosmology, planetary systems, or observational and theoretical methods. For a more targeted approach, consider narrowing by the type of celestial phenomena, level of mathematical detail, or links to related branches like cosmology or particle physics within the broader Physics category.
