Voyager 1

There was some speculation on March 20 that Voyager 1 had actually managed to exit the solar system and enter interstellar space, but other contest that the magnetic field readings have not changed significantly enough to prove this.

This artist's concept shows how NASA's Voyager 1 spacecraft is bathed in solar wind from the southern hemisphere flowing northward. This phenomenon creates a layer just inside the outer boundary of the heliosphere, the giant bubble of solar ion
