Featured Guest: Scott Sheppard

On the hunt for the solar system’s elusive Planet X, a team of astronomers accidentally stumbled upon the discovery of 12 new moons of Jupiter. Oops. But it gets even better, because one of these things is not like the others and the way that moon just doesn’t belong might just solve the mystery of lunar origins. To help us understand how one very happy accident is shedding light on the formation of our solar system, today we’re joined here at The Star Spot by the discovery team leader Scott Sheppard.
