Voyager 1 Might Have Farther to Go to Exit the Heliosheath

The Voyager 1 spacecraft is exploring the outer heliosheath past about 111 astronomical units (AU) from the Sun. The heliosheath is the region where the outgoing solar wind is slowed by the interstellar medium. The Voyager 1 and Voyager 2 spacecraft have been sending back interesting new information about the structure of this previously uncharted [continue reading]
