The Earth and Moon were formed by the unequal collision of two planets some 30-100 million years after the Sun was born. The smaller planet is remembered now mostly by its ghost, but the Earth has grown and prospered. Dr. Zahnle will address the hidden history of the Earth from after the Moon-forming impact until the emergence of a rock record ca 3.8 Ga.
