Supernovae are responsible for producing and distributing the elements at the base of life, specifically oxygen and carbon. Every galaxy should have a certain number of them, according to known distributions. But the Milky Way is a strange exception. Our galaxy comes up far short in its count and that's got scientists wondering where they're all hiding. One possibility is that they're all younger than we'd expected and so we weren't looking in the right places. A newly rediscovered object called G1.9+0.3, located about 26,000 light-years from Earth, could provide the answer.
