Space physics is the study of the physical phenomena that occur in outer space, particularly in relation to celestial bodies and the environment surrounding them. This field examines the behavior of particles, magnetic fields, and radiation in space, helping us understand how these elements interact with each other and with planets like Earth. One key area of space physics is the investigation of the solar wind, a stream of charged particles released from the Sun. Researchers also explore the effects of cosmic rays and magnetospheres, which are crucial for understanding space weather and its impact on technology and life on Earth.
