Farthest 'mini-halo' ever detected could improve our understanding of the early universe

Astronomers discovered a massive "mini-halo" of energetic particles around a distant galaxy cluster while analyzing a 10 billion-year-old radio signal. This unexpected finding, the most distant mini-halo ever detected, could enhance our understanding of the early universe and galaxy formation. The discovery implies that galaxy clusters have been surrounded by charged particles for billions of years longer than previously thought, potentially impacting star formation and other astrophysical processes.
