The origin of these events is hotly debated and popular ideas range from pair instability supernovae to central engine driven explosions. The Pan-STARRS survey, now in full operation, provides an unprecedented opportunity to discovery and study this new class of ultra-luminous at typical redshifts of z~1. Here we propose (non-disruptive) HST Target-of-Opportunity observations of nature's most luminous supernovae to crack the mystery of what powers these beasts. We will trigger on one ultra-luminous SNe discovered with Pan-STARRS at redshifts of z > 0.5 for HST imaging and possible one grism spectrum to search for Halpha. We request a response time of several days to 2 weeks. This is a slow response ToO program.
