When Stars Attack
Nearby Supernovae and Earth
What happens when a massive star reaches the end of its life? It explodes in a brilliant burst known as a supernova, releasing vast amounts of energy and creating the heavy elements that make up the Earth—and even our bodies. Erica Messmer explores the fascinating world of supernovae and their cosmic aftermath.
While the prospect of a nearby supernova may evoke images of a cosmic apocalypse, Erica demonstrates how our Solar System, millions of years ago, actually benefited from the effects of a nearby stellar explosion. She also elucidates the methods astronomers employ to study these powerful stellar explosions, discusses current research endeavors, and explores the implications of these findings for our understanding of our place within the galaxy.
Erica Messmer’s journey to astronomy is far from conventional. Following a decade-long career as a chef, she returned to academia, earning a B.S. in Physics from Northeastern Illinois University. Currently, she is pursuing a Ph.D. in Astronomy at the University of Illinois, focusing her research on supernova remnants. Beyond her academic pursuits, Erica enjoys the companionship of her cats and the meditative practice of knitting.
