This still image and set of animations show NASA's Voyager 1 spacecraft exploring a new region in our solar system called the "magnetic highway." In this region, the sun's magnetic field lines are connected to interstellar magnetic field lines,

NASA's Voyager 1 Probe May Have Left Solar System: Study

NASA's Voyager 1 spacecraft has entered a new region between our solar system and interstellar space, which scientists are calling the stagnation region. This image shows that the inner edge of the stagnation region is located about 10.5 billio
