Astrophysics is a science that employs the methods and principles of physics and chemistry in the study of astronomical objects and phenomena. [1] [2] As one of the founders of the discipline, James Keeler, said, astrophysics "seeks to ascertain the nature of the heavenly bodies, rather than their positions or motions in space—what they are, rather than where they are", [3] which is studied ...

Computational astrophysics – The study of astrophysics using computational methods and tools to develop computational models. Plasma astrophysics – studies properties of plasma in outer space. Space physics – study of plasmas as they occur naturally in the Earth's upper atmosphere (aeronomy) and within the Solar System.
Astrophysics is the branch of astronomy that employs the principles of physics and chemistry "to ascertain the nature of the astronomical objects, rather than their positions or motions in space". [ 73 ] [ 74 ] Among the objects studied are the Sun , other stars , galaxies , extrasolar planets , the interstellar medium and the cosmic microwave ...
