The groundbreaking Voyager 1 spacecraft, zooming ever out of our star , has been ten on a “noisy” interstellar shock wave that it encountered in February of this year, according to the National Aeronautics and Space Administration. The shock wave – caused by long-distance vibrations in the wake of a coronal ejection sent out by our sun – have been continuously emanating out into interstellar space as Voyager 1 rides the wave. These are the same vibrations that first clued in scientists to confirm that the space probe made its historic into space outside the confines of our system. 

The vibrations caused by these coronal mass ejections smash up against the heliosphere, sending out a kind of shockwave that reaches through interstellar space. Normally, these shockwaves are not nearly as long-lived as the one Voyager one has been surfing along, scientists say. these interstellar phenomena are much more than previously thought, according to University of Iowa physics Don Gurnett.
