AMHERST, Mass. – Two astronomers at the University of Massachusetts have observed the remains of exploded stars called supernovae in two "neighbor" galaxies of our own Milky Way. The report on their observations is being presented today by postdoctoral researcher Rosa Murphy Williams and faculty member Q. Daniel Wang, in collaboration with You-Hua Chu and John Dickel of the University of Illinois at Urbana-Champaign, at the meeting of the American Astronomical Society in Albuquerque, N.M. These results provide new insight into the distribution of gas shocked by the supernova blast wave, and the structure of material between stars, the researchers said. The findings expand our understanding of the long-term evolution of a star after it explodes, and of how the remnants of a star are ultimately swept back into the universe.
