Space Video of the Day - 090429

The first billion years of earth's history was a violent time of constant collisions, volcanic eruptions, and acid rain in a crushing atmosphere. Today's space video of the day is an episode of Origins entitled Earth is Born, which looks at those tumultuous first billion years. Update: while updating the
SVOD Archive, I noticed that this is the 500th space video of the day. Yay!
