You may think of inflation as prices creeping higher, but to a cosmologist it's been an important idea to explain why the universe is so uniform on very large scales in every direction we look. But does inflation pass muster as a testable scientific theory? The astroquarks review what inflation is all about as there is renewed discussion in the scientific community about the theory and its predictions. Plus, nerd news and the Great American Eclipse.

The Juno mission is studying Jupiter's interior, but its citizen-scientist JunoCam is returning stunning images of the largest planet. Hear the astroquarks Josh Colwell, Addie Dove and Jim Cooney provide equally stunning descriptions of those pictures. You will hear color! If you're on mind-altering substances. Otherwise it will be a tour of the solar system, from Jupiter to Mars to Comet 67P. All that plus nerd news and space trivia.

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.
