Artificial Intelligence in Computer Science

Stellar Astronomy

• Studies stars, their properties, evolution, and distribution in the universe.
• Examines the composition of stars, primarily hydrogen, helium, and heavier elements.
• Investigates star dynamics, including their movement and interactions within galaxies.
• Explores the life cycles of stars, from main sequence stars to red giants, supernovae, and neutron stars.
• Analyzes different types of stellar systems, including binary stars, star clusters, and galaxies.
• Utilizes optical telescopes, radio telescopes, and infrared telescopes to observe stars.
• Employs spectroscopy techniques to analyze light spectra, determining the composition and temperature of stars.

Cosmology

• The study of the structure, origin, and evolution of the entire universe.
• Key concepts include the Big Bang theory, which proposes the universe originated from an extremely hot and dense state.
• Explores the nature of dark matter and dark energy, which comprise the majority of the universe's energy and matter, while only weakly interacting with ordinary matter.
• Focuses on understanding the behavior of matter and energy at both macroscopic and microscopic scales.
• Observed through cosmological redshifts—analyzing the light from distant galaxies to study the universe's expansion.
• Utilizes gravitational lensing, the bending of light by massive objects, to investigate the distribution of matter.
• Relies on fundamental equations like the Friedmann equations, which describe the dynamics of cosmic expansion.
• Incorporates the cosmological constant, which accounts for the universe's accelerated expansion.
