Forming moon may have taken three big impacts early in Earth’s history
Conventionally, the moon is thought to have formed during one big impact, but a three-impact model might make more sense ...
Billions of years ago, so the theory goes, something around the size of Mars smacked into Earth, spewing a whole bunch of dirt into space that eventually coalesced to form the Moon. This is called the ...
How did the Moon form? Was it from a collision, as has been the longstanding theory, or could it have been captured by the Earth early in our planet’s formation? This is what a recent study published ...
Eons ago, in the frigid depths of our solar system, a dramatic collision occurred between two icy worlds. Instead of a catastrophic smash-up, the two bodies "kissed," merging temporarily like a ...
The research suggests that lunar rock samples from the Apollo missions date to an event that melted the moon's surface — not to the moment it formed. The authors therefore think the moon formed around ...

A Planet Slammed Into Earth 4.5 Billion Years Ago, Forming the Moon. The Projectile May Have Been Our Neighbor
Around 4.5 billion years ago, a planet called Theia is thought to have smashed into newborn Earth. The messy collision kicked ...
New research suggests Earth's Moon formed from the catastrophic collision of our planet with its "sister" planet, Theia, born nearby. This "sibling" planet theory, supported by iron isotope evidence, ...
Earth's calm and cool lunar companion may indeed once have been a roiling ball of molten rock, new research has found. The moon has been long theorized to have formed due to a Mars-sized planet named ...
The Moon might be older than scientists previously thought − a new study shines light on its history
Francis Nimmo has previously received NASA funding relevant to the Moon. A physicist, a chemist and a mathematician walk into a bar. It sounds like the start of a bad joke, but in my case, it was the ...
The moon, Earth’s closest neighbor, is among the strangest planetary bodies in the solar system. Its orbit lies unusually far away from Earth, with a surprisingly large orbital tilt. Planetary ...
