Summary

Story summary

Astronomers identify RAD J131346.9+500320 as the most distant and powerful odd radio circle (ORC) to date, at redshift of about 0.94.
The object displays two intersecting rings, a feature among ORCs.
Researchers from University of Mumbai and RAD@home Astronomy Collaboratory propose these structures arise from host galaxies' superwinds, not black-hole shockwaves.
The findings appear in Monthly Notices of the Royal Astronomical Society, underscoring citizen scientists’ role in modern discoveries.
