Scientists Solve Mystery Surrounding Voyager 1's Passage to Interstellar Space

Ever since NASA's Voyager 1 spacecraft had exited the heliosphere and made the passage to interstellar space, scientists had been perplexed by the spacecraft inconsistent measurements of the galactic magnetic field that lies outside of the Sun's magnetosphere. A new study shows that these Inconsistencies are caused by the deflection of the galactic magnetic field lines from the solar one, at the boundary of the heliopause. Image Credit: NASA/JPL-Caltech
