Introduction to Astrophysics

Astrophysics employs the principles of physics and chemistry to understand celestial objects beyond Earth's atmosphere.

Cosmology is a key aspect of astrophysics that involves examining the large-scale structure and evolution of the universe.

Astrophysicists study the electromagnetic radiation emitted by celestial objects, including visible light, radio waves, X-rays, and gamma rays.

Nuclear physics is a part of astrophysics that explores the nuclear processes and reactions occurring within stars.

Dark matter and dark energy are components of the universe that emit light.

Astrophysics does not involve the study of planetary atmospheres.

The laws of physics, particularly gravity, are not applied in astrophysics to understand the motion and interactions of celestial bodies.

Investigating the origins and fate of the cosmos is not part of astrophysics.

The study of asteroids and comets falls outside the scope of astrophysics.
