Walkabout the Galaxy

Josh and Addie welcome two special guests for this episode of Walkabout the Galaxy where we learn about a new and clever measurement of the size and shape of the heliosphere. Cooler still, some of the critical data came from our old friend Cassini and even older friends the Voyager spacecraft. All this, plus trivia, nerd news and a galaxy-sized wave of hot gas.
