As a Massive star nears the end of its life, it runs out of hydrogen fuel and begins fusing helium. After exhausting its supply of helium it begins to fuse heavier elements until finally, the star's core can no longer exert enough outward pressure and it collapses. A shockwave rebounds through the star so fierce that the star is shredded and leaves behind a small but extremely dense body; either a neutron star or a black hole.
The progenitor of this supernova remnant exploded more than 5,000 years ago and over the course of the past 5 millennia, the material has been racing away in all directions. The Cygnus loop now occupies a vast region of sky, equal to 36 full moons!
A Supernova seeds the interstellar medium with all types of heavy elements. In fact, every single atom of elements heavier than iron was created in this type of event, including many in your own body.
