The groundbreaking Voyager 1 spacecraft, zooming ever onward out of our star system, has been hanging ten on a “noisy” interstellar shock wave that it encountered in of this , according to Aeronautics and Space Administration. The shock wave –  by long-distance in the wake of a coronal mass 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 NASA to confirm that the deep space probe made its historic transition into space outside the confines of our

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