Debris from a supernova explosion that happened about 2.8 million years ago has been found near the Hawaiian Islands.

The debris may have altered Earth's climate, paving the way for human evolution,so they believe.

It stuck me as a bit funny that they reported this since the entire Earth and everything on it is made from Supernova debris.

As a function of stellar evolution, all elements beyond Helium are fused into being inside stars. They can be made nowhere else. Elements beyond Iron are fused by the collapse of a star as it explodes. And the Supernova itself spreads the elements to form whole solar systems, including ours.

Still, it's interesting that they can find specific isotopes which indicate more recent Supernovae debris which has made it to Earth; like rain falling into the ocean. A sprinkling of fresh water into an ocean of saline.
