Astronomers monitoring deep-space radio telescopes have detected repeating Fast Radio Bursts (FRBs) originating from a galaxy more than 1.5 billion light-years away. While magnetars and neutron star mergers are leading natural explanations, the precision of these cosmic pulses keeps stargazers looking up.
Deep Space Signals: Fast Radio Bursts From Distant Galaxies

Millisecond-long pulses of radio waves from billions of light-years away remain one of modern astronomy’s strangest cosmic puzzles.
