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 ...

Over 4.2 billion years ago, the moon turned itself inside out to create the lunar surface that has become familiar to humanity. Most scientists would agree the moon was created around 4.5 billion ...

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 ...

Surprisingly enough, the moon is a piece of our planet. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. The moon is weird. It's completely unlike ...

A crucial difference in the “fingerprints” of Earth and the moon confirms an explosive, interconnected past Within the first 150 million years after our solar system formed, a giant body roughly the ...

We already know a decent amount about how planets form, but moon formation is another process entirely, and one we're not as familiar with. Scientists think they understand how the most important moon ...

Using advanced models, SwRI led new research that indicates that the formation of Pluto and Charon may parallel that of the Earth-Moon system. In the resulting “kiss-and-capture” regime, Pluto and ...

The Moon formed a little later than previously assumed. When a Mars-sized protoplanet was destroyed in a collision with the young Earth, a new body was created from the debris ejected during this ...

A pair of NASA spacecraft detected tiny variations in the Moon's gravitational pull, which may be the result of a dense layer sinking to the bottom. Reading time 2 minutes During its early years of ...

"For the first time, we have physical evidence showing us what was happening in the moon's interior during this critical stage of its evolution, and that's really exciting." When you purchase through ...
