NASA says the sand on Earth may have come from space

We're constantly having to rethink our planet and our own place in the universe. As our understanding of how our world was formed, millions of years ago; so our knowledge for the search for life elsewhere, increases.

Nasa has already revealed that parts of Earth may actually be Martian in origin or deposited by passing comets during the Solar System's early formation. But the latest study, could help us understand just how rocky planets, like the Earth, are formed.

A new study by the space agency has revealed the surprising origin of the sand in our deserts and on our beaches. The main element that makes up this sand comes from a lot further away than we think and was actually created at the heart of a supernova.
