Billions of years ago, a version of our Earth that looks very different than the one we live on today was hit by an object about the size of Mars, called Theia – and out of that collision the Moon was ...

It’s believed that the Moon formed billions of years ago, from debris from a cosmic collision with Earth. New high-resolution simulations not only illustrate the idea in stunning detail, but reveal ...

Cast your mind back to when Earth was a baby. The solar system was a brutal nursery. Giant fragments of rock whirled chaotically around a fiery young sun, regularly bombarding infant planets. Earth ...

Astronomers have taken a step towards understanding how the Moon might have formed out of a giant collision between the early Earth and another massive object 4.5 billion years ago. Scientists led by ...

The story of creation, whether of worlds or moons, has long fascinated humanity. For decades, most scientists agreed that the Moon was born from a violent collision between Earth and a Mars-sized body ...

A new supercomputer simulation shows the moon's possible origin. Space experts have been studying samples from the Earth's natural satellite for the past few years. A Super Blood Wolf Moon is seen ...

The formation of the Moon billions of years ago is cloaked in mystery. Most astronomers believe the young Earth, still cooling off from its formation, was struck by a mars-sized body called Theia, ...

Learn more about the time when the moon didn’t exist, and then hours later suddenly did. Einstein once asked whether “the moon exists only when I look at it?". It was rhetorical objection to the idea ...

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 ...

Most theories claim the Moon formed out of the debris of a collision between the Earth and an object about the size of Mars, called Theia, coalescing in orbit over months or years. A new simulation ...
