"Newly Discovered Supernova Remnant Unveiled by Astronomers"

Astronomers from Curtin University and other institutions have discovered a new supernova remnant (SNR) named G321.3-3.9, located 3,300 light years away. The elliptical SNR is estimated to be a few thousand years old and was confirmed using radio and X-ray data. The SNR's distance, diameter, and age were estimated, but uncertainties remain due to limited data. Further observations are planned to search for a pulsar association, which could provide more accurate measurements of the SNR's properties.
