From the Bad Astronomer

It takes a great bit of luck to catch a supernova just when it explodes. That happened recently, and Dr. Phil writes about it. It's really freaking cool.

The hemoglobin in your blood, the bones in your body, and the
wedding ring on your finger — all of these can trace their lineage back
to a star that exploded like SN2008D. Every heavy element in the
Universe was created in such an event, in the heart and fury of a
supernova.

We owe our very existence to stars that explode.
