WebApr 12, 2024 · Solar cosmic radiation is composed of charged particles emitted by the Sun, predominantly electrons, protons and helium nuclei. Some of this radiation is continuously emitted from the Sun’s corona, which led scientists to call it the ‘solar wind’. The remainder comes from solar particle events ... WebThe Solar Wind Electrons Alphas and Protons (SWEAP) investigation is the set of instruments on the Parker Solar Probe (PSP) spacecraft that will directly measure the properties of the plasma in the solar atmosphere.
