Dust factory in a dead star

Interstellar space dust from a dead star identified by a research team led by The University of Nottingham could unlock some of the mysteries of the early universe. Dr Loretta Dunne and her team have found new evidence of huge dust production in the Cassiopeia A supernova remnant, the remains of a star that exploded about 300 years ago. The paper is set to be published in the Monthly Notices of the Royal Astronomical Society.

It is responsible for the dark patches seen in the Milky Way on a moonless night.
