‘Extragalactic immigrants’: We’re all made from far-away star dust, scientists say


‘Astronomers studying the galaxy formation have theorised that up to half of all matter that makes up our Milky Way came from far flung regions of space – meaning that us and everything around us are extragalactic immigrants.’

When a star dies it creates a supernova, a massive explosion which results in the expulsion of most of the stars mass, it’s matter, and atoms which make up this matter. These atoms are sent hurtling through space being transported from one galaxy to another on “powerful galactic winds.”
