Scientists have gone back and forth about explanations for the moon's formation for decades, with the general consensus being that it formed during some type of cosmic collision between Earth and a ...

(CNN) – The moon may be 100 million years older than planetary scientists thought. The moon has long been thought to have formed roughly 4.35 billion years ago after a Mars-sized object collided with ...

Two primary theories explain planetary moon formation: gravitational capture within a planet's Hill sphere radius and simultaneous formation with the solar system during its accretion disk phase. A ...

Apollo samples provide evidence: Researchers analyzed Moon rocks brought back by the Apollo missions and, for the first time, used their iron isotope ratios to trace where Theia originally formed.

Scientists have identified volcanic glass beads in lunar soil samples, indicating that volcanic activity continued on the ...
