We once thought that our solar system was unique: The only place you could find planets in the entire Universe. Now we know better. For the last twenty years we have been discovering planets at an amazing rate, but they are nothing like we expected. These are truly wild worlds, a collection of monsters. From deep-frozen, toxic snowballs, to scorched and boiling nightmares: Every one is worlds apart from the habitable paradise we know and love here on Earth. Having so far only discovered this zoo of planetary oddballs we must face the question: Is every planet out there a planet from hell?

Before moving on from Jupiter to Saturn, we’re going to linger for a moment on Jupiter’s moons. There are 67 known moons, and 4 huge ones that we want to explore in greater detail. Ganymede is the largest - larger, in fact, than any other moon in the solar system and the planet Mercury! Callisto, orbiting the farthest out, is smaller but quite similar to Ganymede in many ways. Io, meanwhile, is most noteworthy for its tremendous volcanic activity. There’s also water on Ganymede and Europa!

Twenty years after its launch, we bid farewell to the Cassini spacecraft as it plunges into Saturn’s atmosphere in a planned death spiral. Productive right to the end, Cassini has rewritten the textbook on not only Saturn and its moons, but our whole solar system as well.

What if you could get behind the wheel and race through space? We scale down the Solar System to the continental United States and place the planets along the way to better appreciate the immense scale of the Universe. See space as never before, with Mars looming over the Freedom Tower and Jupiter towering above the Lincoln Memorial. Join former astronaut Chris Hadfield - a YouTube sensation for his performance of David Bowie’s “Space Oddity” aboard the International Space Station - and his interstellar hitchhikers Michio Kaku and astronomers Derrick Pitts and Laura Danly. It’s a joyride from coast to coast - and from the sun to Pluto.

NASA has taken us to the outer reaches of our Solar System, but there are still many mysteries to explore. New probes are being designed to look at our sun, the deep oceans of icy moons, and perhaps even our closest neighboring system - Alpha Centauri.
