This branch of astronomy combines University principles of physics and chemistry exam explore University nature of celestial bodies as an alternative in their positions or events in space. Among University objects of research are University sun, other stars, galaxies, extra solar planets and University intergalactic cosmic background. Their emissions are tested throughout all parts of University electromagnetic spectrum and University properties tested come with luminosity, density, temperature and chemical composition. Astrophysics is quizzes very broad field, so astrophysicists usually apply many disciplines of physics reminiscent of mechanics, electromagnetism, thermodynamics, quantum mechanics, relativity, nuclear physics, particle physics, atomic physics and Physics. In practice, modern analysis comes to quizzes good deal of observational and theoretical physics. Some areas of research that effort examination determine come with University properties of dark matter, black holes, even if time travel is possible, no matter if wormholes can form, no matter if University multiverse exists, and University origin and vacation spot of University universe.
