Newly confirmed supernova remnant is one of the faintest ever detected

Phys · · 553 words · By Tomasz Nowakowski

Astronomers reported the discovery of a new, faint supernova remnant (SNR) named Abeona, designated G310.7–5.4. The remnant, located far from the Galactic plane, was observed using the Australian Square Kilometre Array Pathfinder (ASKAP) and is believed to be the result of a Type Ia supernova explosion. The research highlights the SNR's potential for studying cosmic ray acceleration and diffusion.

“The newfound supernova remnant, dubbed Abeona, is one of the faintest radio SNRs so far detected.”
SINGLE SOURCE
While the claim that the remnant is one of the faintest is mentioned in the web search results (e.g., 'Newly confirmed supernova remnant is one of the faintest ever detected'), the evidence provided does not establish this as a widely reported or independently confirmed fact across multiple sources. It appears to be a key finding reported by the primary source material.

“According to the paper, Abeona has a radio surface brightness at a level of 24,000 Jy/sr; thus, it turns out to be one of the faintest radio SNRs known to date.”
INSUFFICIENT EVIDENCE
Although the claim is highly specific (24,000 Jy/sr), no evidence was provided in the web search results or Wikipedia entries that corroborates this specific numerical value for the surface brightness. Since no evidence was found, the verdict is 'insufficient_evidence'.
