Astronomers discover new supernova remnant

Astronomers from Curtin University in Australia and elsewhere report the detection of a new supernova remnant (SNR) located some 3,300 light years away. The newfound SNR, designated G321.3-3.9, has an elliptical shape and is estimated to be a few thousand years old. The finding was detailed in a paper published Jan. 30 on the pre-print server arXiv.
