In a new study using data from the CALorimetric Electron Telescope (CALET) instrument on the ISS, the researchers have found evidence for young and nearby sources of cosmic ray electrons, which are a special kind of cosmic ray that carry a negative charge. These sources will likely be the remnants of exploded stars, or supernovae, in our galactic neighborhood.
