Excerpt from

The groundbreaking Voyager 1 spacecraft, zooming ever onward out of our star , has been hanging on a “noisy” interstellar shock that it encountered in February of this year, according to the Aeronautics and Administration. The shock wave – caused by long-distance vibrations in the wake of a sent out by our sun – have been 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 into space outside the confines of our solar system. 

The vibrations caused by these coronal mass ejections smash up against the heliosphere, sending out a 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. Apparently these interstellar phenomena are much more common than previously thought, according to University of physics professor Don Gurnett.
