Abstract


Cosmic dust has a huge impact on our view of the Universe, yet its origin is still a mystery. Massive stars, which live fast and die young, culminating in an explosion (supernovae), could provide a rapid source of dust grains and explain the dusty galaxies seen in the early Universe.  Our observations which detected heat directly from cool dust suggest
