Voyager probes reveal a new form of cosmic rays emanating from the Sun.


Voyager probes still contribute to science more than 40 years later and billions of miles from home. Researchers have discovered a new way to electron beam electron beams using instruments on board Voyager 1 and 2. The displacement of the coronal mass from the Sun produced shock waves, which first manifested themselves as waves of electrons at almost the speed of light, followed by plasma waves and then the shock waves themselves.

Electrons appear to be directed after they have reflected a strong magnetic field at the edge of the shock wave, accelerating and conducting the electrons, respectively, to the motion of the waves and the lines of the interstellar magnetic field. The concept is not new (it happens with solar winds), but scientists have not seen interstellar shock waves in such a new environment.
