About this show

The New Horizons spacecraft gave us our first close look at Pluto, the most famous dwarf planet in the outskirts of our Solar System. We are making new discoveries about how our Solar System formed – and what it may be hiding. Follow Mike Brown and his team at CalTech as they uncover dwarf worlds like the remarkably bright Eris; Haumea, an egg-shaped object rotating incredibly fast; and Sedna, whose orbit takes it deep into the far reaches of the Solar System. Is there a new planet beyond these distant objects? We’ll tag along on Mike Brown’s first night searching for the ninth planet at the Subaru Telescope in Hawaii.
