We are all made of stardust

We are all made of stardust

This may sound fanciful, but the reality is almost every element found on Earth was created in the burning core of a star, all the stuff that makes up life on Earth, therefore our bodies are made from stardust. NASA have studied stardust extensively, and you can read more about their research on their official website. A NASA stardust canister is pictured above.

In the words of Carl Sagan, “The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff.”
