Astronomy & Astrophysics

Astronomy and Astrophysics is the scientific discipline that investigates celestial objects and cosmic phenomena using both observational and theoretical approaches. The field encompasses a wide range of structures and processes, including stars, planets, galaxies, black holes, neutron stars, active galactic nuclei, and the cosmic microwave background.

Key research topics include the physical properties of these objects—such as luminosity, mass, chemical composition, temperature, and spectral characteristics—as well as their formation, evolution, dynamics, and interactions. The discipline also involves time-series analysis, multi-wavelength observations, numerical modeling, and high-energy astrophysics techniques.

Planetary science, stellar evolution, cosmology, galactic dynamics, the structure of space-time, and high-energy cosmic events all fall under the broad umbrella of Astronomy and Astrophysics. The field is inherently interdisciplinary, drawing upon physics, mathematics, statistics, and engineering.
