| Voyager mission finds a new type of electron burst at the edge of our solar system
By Carly Cassella - ScienceAlert
The Voyager probes left our Solar System years ago, yet even as they travel through interstellar space, they are still detecting bursts of cosmic rays from our Sun, more than 23 billion kilometers (14 billion miles) away.
A detailed analysis of recent data from both Voyager 1 and Voyager 2 has now revealed the first bursts of cosmic ray electrons in interstellar space.
Carried to the fringes of our Solar System by the shock waves of solar eruptions known as coronal mass ejections, these energized particles appear to accelerate even beyond the borders of our Sun's powerful winds.
"The idea that shock waves accelerate particles is not new," notes astrophysicist Don Gurnett from the University of Iowa.
