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.
Is the universe just a simulation? Simon says maybe. Then Tony settles the question of the habitability of potential water worlds. And speaking of water, Dave ponders the origin of our own planet’s H20.

Featured Guest: André Müller
Astronomers have taken their first image of an infant planet still developing around a newly formed star. Today we’re joined here at The Star Spot by André Müller, whose team is busy studying this baby world and has already discovered evidence of an atmosphere and possibly even moons, astounding knowledge of such a tiny speck 370 light years from Earth.
On a personal note, I want to dedicate this special 150th episode of The Star Spot to my amazing wife Denise and to our own newborn wonder, Lara Fong Trottier. Thank you for being the stars in my universe.

What secrets are hiding in the darkness on the moon? Tony sheds some light. And have you ever wondered just how we arrive at the mass of those thousands of extrasolar planets astronomers are busy studying?
