An international group of researchers has used the GTC to observe a superluminous supernova almost from the moment it occurred. It has revealed surprising behaviour, because this supernova showed an initial increase in brightness which later declined for a few days, and later increased again much more strongly. The scientists have used the data observed at the GTC and has combined them with other observations to try to explain the origin of the phenomenon.
