“The Planets: Ice Worlds”

Aired Thursday 15 August 2019

Over a billion miles from the sun, beyond the rocky inner planets and the gas giants, lie the ice words—Uranus and Neptune. NOVA takes you inside the missions that rewrote the story of the outer solar system: NASA's Voyager 1 & 2 capture Neptune's supersonic winds, rings around a tipped-over Uranus, and dozens of moons. And when New Horizons flew by Pluto in 2015, it reveals jagged ice mountains and an underground ocean before venturing deep into the Kuiper Belt.
