The Combination of Astrophysics and Astronomy resolving the mystery of Dark matter, Dark energy and Black holes

 Astrophysics is a branch of science that applies the techniques and principles of physics in the study of astronomical things and phenomena. The subjects of the study are the Sun, other stars, galaxies, extrasolar planets, the interstellar medium and the cosmic microwave background radiation. Radiations from these objects are tested across all parts of the electromagnetic spectrum, and the other properties tested include luminosity, density, temperature, and chemical structures. As we know astrophysics is a very common  subject, astrophysicists employ principles and methods from many branches of physics, including electromagnetism, classical mechanics, statistical mechanics, thermodynamicsrelativity quantum, mechanics, nuclear and particle physics, and atomic and molecular physics.

Generally, advanced astronomical research tries to involve a substantial level of work in the sectors of theoretical and observational physics. There are also some areas of study for astrophysicists include their practices to evaluate the properties of dark matterdark energyblack holes, and other interstellar bodies; and the origin and recent belief of the universe. Researches studied by theoretical astrophysicists involve Solar System formation and evolutionstellar phenomenon and evolutiongalaxy origination and evolution; large-scale structure of mattermagnetohydrodynamics in the visible and invisible universe; birth of cosmic rays; special relativity, general relativityquantum and astrophysical cosmology, including string cosmology and particle physics.
