A Mars-sized world smashed Earth, five hours later, the Moon was born
Billions of years before life, oceans and continents, the young Earth suffered a planet-sized collision. A new Southwest Research Institute-led study suggests that a Mars-sized body could have smashed into Earth and produced an intact Moon in as little as five hours. The finding could dramatically change our understanding of one of the Solar System's most violent events and the mysterious birth of our Moon.
