Fact Sheet
Heading Out
An artist's concept shows the Voyager 2 spacecraft leaving the magnetic 'bubble' that surrounds the solar system and entering a turbulent region where interstellar magnetic fields over the Sun's. Voyager has found that the magnetic bubble, known as the heliosphere, is squeezed inward toward the Sun more on the southern side than the northern side. A spacecraft scheduled for launch later this year will try to map this boundary region from Earth orbit, while Voyager 1 and 2 continue to probe the region as they exit the solar system. [NASA]
