Birth of the Moon PREVIEW
Coming soon to “Cosmic Journeys.” Earth, over its 4.5 billion year history, has been pummeled by asteroids, eroded by wind and rain, covered over with flowing lava, wrinkled and gouged by shifts in its crust.
Most traces of its distant past have long since been destroyed. But there is a place where clues to the early history of our planet are still largely intact.
Scientists have been reconstructing its history by scouring its surface, mapping its mountains and craters, and probing its interior regions.
What are they learning about our own planet’s beginnings, by going back in time, to the mysterious “Birth of the Moon.”
