About this work
This set of graphs illustrates how data from two key instruments point to NASA's Voyager 2 spacecraft entering interstellar space, or the space between the stars, in November 2018. The top two plots come from the plasma science experiment (PLS). The plasma -- or ionized gas -- of interstellar space is significantly denser than the plasma inside the bubble of plasma the Sun blows around itself (the heliosphere). There is a jump on the graph in November 2018.
