Spotting a supernova is incredibly rare, and in 1995, the observatory at Saint Mary's University in Halifax earned itself an enviable distinction when two Canadian astronomers discovered a supernova in a galaxy 70 million light years away! This breathtaking coin captures the magic of the event with a borosilicate glass insert. The globule is so refined, it's like gazing through a telescope, with a one-of-a-kind view that can only be created with handcrafted artistry.
