Launched in September 1977, NASA’s Voyager 1 spacecraft flew by Jupiter in 1979 and then Saturn in late 1980. In August 2012, it crossed the heliopause and became the first in situ probe of the very local interstellar medium. Now, using data from the Plasma Wave System on Voyager 1, a team of researchers from Cornell University and the University of Iowa has detected very weak plasma wave emission in the interstellar medium.
