No cold dust within the supernova remnant Cassiopeia A
Article Abstract:
A report on a large amount of cold dust in the prototypical type II supernova remnant Cassiopeia A is presented. It concluded that dust production in type II supernovae could explain how the large quantities of dust observed in the most distant quasars could be produced within only 700 million years after the Big Bang.

A supernova origin for dust in a high-redshift quasar
Article Abstract:
The infrared observations of a quasar at redshift 6.2 are reported, that are used to obtain directly its dust extinction curve. The results demonstrate a supernova origin for dust in high-redshift quasar, from which it is assumed that most of the dust at high redshifts probably have the same origin.
