One of the biggest mysteries to solve in ‘Astro-particle physics’ has been to find out source of origin of ultrahigh-energy cosmic rays, very high-energy neutrinos and high-energy gamma rays.[1] All energetic charged particles coming to earth and originating from any source are conventionally called ‘cosmic rays’. Few ‘cosmic rays’ moving at the speed of light are reported to be coming from Sun and out side of the solar system, from supernovas in our galaxy, galactic centre or from far off galaxies while abundant lesser energy charged particles coming to our atmosphere have different sources which should be explored. Some of the high energy charged particles reaching Earth are generated in the Sun and there number becomes significant during periods of solar flare. “It has been observed that Jupiter is absorbing a lot of sulfur from its volcanic moon Lo, and the gigantic magnetosphere of Jupiter generates billions of volts of electric field and energetic charged particles. In one study based on Galileo probe data, the presence of He ion as tracer for solar wind, sulfur ions coming from its natural satellite ‘Lo’ and oxygen ions coming from Jovian atmosphere itself, were studied. The charged particle acceleration mechanisms in Jovian magnetosphere were reported as ‘Alfven waves’, noadiabatic ion interaction with current sheet and by induced current fields”. [2] Could these magnetospheres of all planets (except Venus and Mars which are devoid of magnetospheres) and few natural satellites of planets having magnetospheres can trap and generate energetic charged particles apart from low energy cosmic rays in our solar system apart from high energy charged particles are coming from our Sun? Let us first study the possible mechanism of generation of energetic charged particles in our magnetosphere itself. Our aim will be to find out that from where the magnetosphere of Earth gets raw material for generation of charged particles? What is the mechanism of their production? How Magnetosphere can provide these particles, so much energy that they acquire the nature of cosmic rays?
