Could there be a monstrous, undiscovered star orbiting our own Sun? Could it be scattering killer comets throughout our Solar System like clockwork every 26 million years? New scientific surveys are probing the edges of our Solar System--a realm populated by giant worlds and mysterious planetoid--hunting for Nemesis, the Sun's purported evil twin. We may be on the verge of discovering this ultimate death star, suspected of causing every mass extinction in Earth's history. We employ everyday experiences to explain what Nemesis is and why it's been so hard to find. Experts start a wildfire on a dry California hillside, race a NASCAR around an oval track, and juggle fire, all in the effort to present how Nemesis works, and why life on Earth may depend on its discovery.
