After a supernova explosion, a neutron star neutron star remains: a city-sized ball of unimaginably dense matter, spinning hundreds of times per second. Any tiny bump on its surface would make it wobble like an off-balance spinning top, humming faintly through the fabric of space.

For almost twenty years, FRB (fast radio bursts) have intrigued astrophysicists — millisecond shrieks from the depths of space, carrying the energy of millions of Suns.

In 2007, astronomers heard a mysterious millisecond click from space — that's how fast radio bursts, or FRBs, were discovered. Since then, they've become a cosmic-scale detective story: as bright as an entire galaxy and compressed into an instant, these signals race through the Universe at the speed of light.
