The discovery of gravity waves in early 2013 was huge news around the world ... and so was the retraction after the scientists realized they'd made a mistake. This is a dramatic human story of brave scientists and big science in action at the South Pole.

We have traveled into space and looked deep into the universe’s depths, but the world beneath our feet remains unexplored and unseen. Now, that’s about to change. For the first time in one epic unbroken shot, we embark on an impossible mission – using spectacular computer generated imagery to smash through three thousand miles of solid rock, and venture from our world into the underworld and on to the core of the Earth itself.

Now that we’ve finished our tour of the planets, we’re headed back to the asteroid belt. Asteroids are chunks of rock, metal, or both that were once part of smallish planets but were destroyed after collisions. Most orbit the Sun between Mars and Jupiter, but some get near the Earth. The biggest, Ceres is far smaller than the Moon but still big enough to be round and have undergone differentiation.
