Scientists solve a long-standing mystery surrounding the moon's 'lopsided' geology

About 4.5 billion years ago, a small planet smashed into the young Earth, flinging molten rock into space. Slowly, the debris coalesced, cooled and solidified, forming our moon. This scenario of how the Earth's moon came to be is the one largely agreed upon by most scientists. But the details of how exactly that happened are "more of a choose-your-own-adventure novel," according to researchers in the University of Arizona Lunar and Planetary Laboratory who published a paper in Nature Geoscience.

A newly refined map of Zealandia drawn using study of dredged rock samples

A small international team of geologists and seismologists has created a newly refined map of Zealandia using data obtained from dredged rock samples recovered from the ocean floor. They report details in the journal Tectonics.
