Worst Days on Planet Earth

Today on Far Future Horizons we look at some of the worst days that have plagued our planet during its 4.54 billion years in another exciting episode of the acclaimed documentary series The Universe.

Earth may seem like the most hospitable planet in the solar system. But look again. Startling new discoveries reveal the blue planet has been plagued by more chaos and destruction than scientists once imagined. 

Stand on the Earth billions of years ago as a primitive protoplanet slams into it. Shiver as our entire globe is frozen over like a gigantic snowball. Feel the heat as mammoth volcanoes scorch the landscape and darken the sky. 

From a cosmic gamma ray burst frying away the ozone layer to an Everest-size asteroid slamming into the ocean, we'll reveal new information about how these unparalleled events drove life to the brink of total extinction.

Out of this continuous devastation, how has our planet and life got to where it is today? Are the worst days behind us or are more dark days lurking in the distant future?

The Universe is available on DVD from Amazon.com and the History Channel’s online store.
