Cluster statistics suggest that about 60% of stars form in groups with more than 1000 members. Such large groups are expected to contain at least one massive star that will undergo a supernova within the average circumstellar disk lifetime of 3 Myr. The Orion proplyds are the closest example of such an environment. I will present the first mass measurements of the dust in these disks from observations at 880 microns with the Submillimeter Array that show that sufficient material exists in several objects to form planetary systems on the scale of our Solar System. The presence of the short lived radionucleide, 60Fe, in meteorites shows, unambiguously, that at least one supernova exploded close to either the collapsing core that formed our Sun or the planetary disk itself. Gathering recent information on young embedded clusters, I show a simple analytical model and Monte Carlo simulations that estimate the likelihood of supernova enrichment of a young circumstellar disk. I conclude the likelihood is only a few percent under a range of star formation scenarios and discuss the implications for reconciling the meteoritic and astronomical evidence of our origins.
