Story summary

A potential orphan afterglow from a gamma-ray burst was identified as ASKAP J005512-255834 using the Australian SKA Pathfinder telescope.
The source is about 1.7 billion light-years away and emitted vast energy while showing little signal in other wavelengths.
Researchers ruled out other explanations.
If confirmed, the finding may lead to more orphan afterglows and enhance understanding of gamma-ray bursts.
