Abstract:

The solar wind flows from the Sun and carves out a bubble in the interstellar medium called the heliosphere. The Voyager spacecraft are making the first observations of the magnetic fields, particles, and waves near the heliopause, the outer boundary of the heliosphere. Voyager 1 has probably crossed the heliosphere and entered the interstellar medium.
Voyager 2 is still in the heliosheath but observing very different plasma flows than observed at Voyager 1. I will present and discuss these data from the outer regions of our heliosphere.
