Giant Moon-Forming Impact On Early Earth May Have Spawned Magma Ocean
Billions of years ago, the Earth’s atmosphere an opaque and the planet’s surface was a vast magma ocean devoid of life.
This scenario, says Stanford University professor of geophysics Norman Sleep, was what the early Earth looked like just after a cataclysmic impact by a planet-size object that smashed into the infant Earth 4.5 billion years ago andformed the moon.
