We know that in the centres of the majority of galaxies lies a supermassive black hole. New observations of certain galaxies reveal that these black holes may be consuming stars at a higher rate than previously known. The energy produced by the destruction of the star can be revealed in the infrared, as heat from cosmic dust warmed by the explosion.
 

Stars over eight times more massive than the Sun end their lives in supernovae explosions. The composition of the star influences what happens during the explosion.
