The recently-discovered, nearby young supernova remnant in the southeast corner of the older Vela supernova remnant may have been seen in measurements of nitrate abundances in Antarctic ice cores. Such an interpretation of this twenty-year-old ice-core data would provide a more accurate dating of this supernova than is possible purely using astrophysical techniques. The resulting estimates of the supernova distance and light-arrival time are 200 pc and 700 years ago, implying an expansion speed… CONTINUE READING
