For around forty years, astrophysicists have observed the annihilation of positrons in the Galaxy at a prodigious rate. ... The fact the Galactic bulge far outshines the disk in annihilating positrons which are injected into the ISM at low energies makes the source of the positrons difficult to identify, as the main source of such positrons are prima facie located in the Galactic disk. ...

... There is no question about the source of ionospheric plasma , since it is created from the ambient neutral atmosphere by ionization. However, the source of magnetospheric plasma is a much more complicated question: although it seems obvious that both solar wind and ionosphere feed it, the relative importance of these two sources is unclear. ... Protons (H + ) are the primary ions in solar wind and one of the major components in ionospheric outflows, and thus not good indicators of their source. ...
