Fast radio bursts (FRBs) last around a millisecond and in doing so encode otherwise unattainable information on the plasma which permeates our Universe, providing insights into magnetic fields and gas distributions.

In a paper authored by Manisha Caleb from the University of Sydney, the team report upon the discovery of FRB 20240304B which lies at a redshift of 2.148 +/- 0.001, corresponding to just 3 billion years after the Big Bang .

The burst, designated FRB 20240304B, was first detected on March 4, 2024, by South Africa's MeerKAT radio telescope array. What makes this discovery extraordinary is its incredible distance, at a whopping redshift of z = 2.148±0.001, or about 3 billion years after the Big Bang. This means we're observing light that traveled for over 11 billion year
