DOI: 10.48550/arxiv.2604.19897 An international team of astronomers reports the discovery of a new supernova remnant (SNR) using radio observations. The newfound supernova remnant, dubbed Abeona, is one of the faintest radio SNRs so far detected. The discovery is detailed in a research paper published April 21 on the arXiv preprint server. SNRs are the remains of a supernova explosion, observed as diffuse, expanding structures. Studies indicate that SNRs harbor ejected material expanding from the supernova explosion. They also contain other interstellar material that has been swept up by the passage of the shockwave from the exploded star. Named for a Roman goddess Now, a team of astronomers led by Christopher Burger-Scheidlin of the Dunsink Observatory in Ireland reports the discovery of a new supernova remnant using the Australian Square Kilometre Array Pathfinder (ASKAP).…
