Wham! Go the Planets

We recorded Episode 17 on the day of Joan Rivers’ death, which inspired us to imagine science fashion police. On the science front, Josh, Addie and Tracy talk about this discovery of the splashy remnants of what the study authors can only imagine was the collision of two planet-sized objects. The system in question is a young star similar to the Sun, but only about 35 million years old (the Sun is 4.55 billion years old, give or take a week), so it’s tempting to imagine this collision as similar to ones that certainly occurred in our own system, such as the one that created the Moon. As always, episodes can be downloaded from iTunes here.
