Are we made from stardust?
Yes. All the atoms in your blood, calcium atoms in your bones and oxygen atoms in your lungs are older than the Earth and
were once at the heart of a giant star. The Universe was born with just hydrogen and helium.
Even today, these two elements make 98 per cent of all the atoms in the cosmos. Just two persent of this reservoir
has been converted into the other chemical elements found in nature. To transmute chemicals like this requires the sort of
temperature and pressure found within stars. The elements are then scattered back into space at the end of a star's life.
So, apart from some of the hydrogen in our bodies, all the other atoms were once at the center of a star.
