A new simulation of how the Moon formed shows that it could have formed in the span of mere hours, NASA says. Billions of years ago, when Earth was much younger, it would have looked a lot different ...

New study provides clearer insight into how the Moon formed and why its materials closely resemble those of Earth.

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 ...

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 ...

Because the Earth is doing the work of increasing the Moon's momentum, the Earth's rotation slows down in turn, as its ...

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 ...

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 ...

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 ...

A computer simulation that traces the moon’s formation in high resolution may explain the mystery of why it is so chemically similar to Earth. The conventional story for the moon’s origin is that a ...

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 ...

An international research collaboration has used advanced computer simulations to investigate how faint radio signals from ...

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 ...
