WtG is hosted by Josh Colwell, Addie Dove, and Jim Cooney. All three are in the Physics Department and the Florida Space Institute at the University of Central Florida . Josh and Addie study dust, rings, comets, moons, asteroids and planet formation, and they try to drag Jim into their planetary escapades, but his passion is cosmology.
Here are Jim and Addie during an early WtG recording session. (We have better microphone stands now.)
Here is what Josh looked like when this picture was taken. Usually he looks more like Brad Pitt. Basically, just take a look at a picture of Brad Pitt to get an idea, and keep that image in mind when listening to the podcast.
