“Supernova ash has been found in fossils created by bacteria
here on Earth. The discovery, published on August 10 in the
Proceedings of the National Academy of Sciences journal,
suggests a link between an explosion of a star and an
extinction event on our planet over two million years ago.”

The paper is:

2-million-year-old supernova activity discovered in Earth’s
