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. The Week That Was sponsored by Suitmate. The reflected electrons then spiral along interstellar magnetic field lines, gaining speed as the distance between them and the shock increases. Are we sure that the solar rays we are detetcting are fromour own Sun or from another much bigger Star?

However,the questions we are asking should be looking for other possible explanations as well. Even at those speeds, it takes more than a year for the shock waves to reach the Voyager spacecraft, which have traveled further from the sun (more than 14 billion miles and counting) than any human-made object.
