New submitter ihtoit writes "Astronomers using the ALMA radio telescope in Chile have released images and data showing the oft-postulated but unobserved (until now) dust shell ejected by the supernova remnant SN1987A. 'We have found a remarkably large dust mass concentrated in the central part of the ejecta from a relatively young and nearby supernova,' astronomer Remy Indebetouw, of the National Radio Astronomy Observatory (NRAO) and the University of Virginia, said in a statement. 'This is the first time we've been able to really image where the dust has formed, which is important in understanding the evolution of galaxies.' SN1987A was the first cataloged supernova event in our Galactic neighborhood in 1987. It lies 168,000 light years (987 quadrillion miles) away in the Large Magellanic Cloud, which means that at the time of the explosion, woolly mammoths still roamed Europe and Mitochondrial Eve saw her first sunrise." From the article, the significance: "'Really early galaxies are incredibly dusty and this dust plays a major role in the evolution of galaxies,' Mikako Matsuura, a scientist associated with the study ... said ... 'Today we know dust can be created in several ways, but in the early universe most of it must have come from supernovas. We finally have direct evidence to support that theory.'"
