Space: Fast Radio Burst [FRB] Reaches Earth After Travelling 10 Billion Years! (23.9.2025)

Why cosmic noon matters

The burst came from a time nicknamed “cosmic noon,” when the universe was forming stars at its fastest rate.

Astronomers see a peak in the cosmic star formation history about 10 to 11 billion years ago, and this event sits in that era.

Finding an FRB there matters for more than a date on a timeline. It shows that whatever powers FRBs was active when young galaxies were busy building their stars.

“This discovery doubles the redshift reach of localized FRBs. Our observations establish FRB activity during the peak of cosmic star formation” wrote Caleb.
