Astrophysics

 Astrophysics is the branch of astronomy that deals with the physics of the universe, mainly with the nature of the heavenly bodies, alternatively than their positions or motions in space. Astroparticle physics, additionally regarded as particle astrophysics, is a department of natural philosophy that studies fundamental particles of astronomical origin and their relation to Astrophysics, Cosmic ray physics, astronomy, Cosmology and Particle physics. It is quite a new subject bobbing up at the interplay of particle physics, astronomy, astrophysics, detector physics, relativity, stable kingdom physics, and cosmology. Partly driven with the aid of the invention of neutrino oscillation, the subject has gone through quick development, both in idea and experiments.
