Voyager spacecraft detect new type of solar electron burst

More than 40 years since they launched, the Voyager spacecraft are still making discoveries.
In a new study, a team of physicists led by the University of Iowa report the first detection of bursts of cosmic ray electrons accelerated by shock waves originating from major eruptions on the sun. The detection, made by instruments onboard both the Voyager 1 and Voyager 2 spacecraft, occurred as the Voyagers continue their journey outward through interstellar space, thus making them the first craft to record this unique physics in the realm between stars.
These newly detected electron bursts are like an advanced guard accelerated along magnetic field lines in
