Scientists are tracking strange cosmic signals called fast radio bursts—and their origins remain unclear.

Astronomers are picking up mysterious pulses from deep space, and no one is completely sure what’s causing them. Known as fast radio bursts (FRBs), these flashes of energy are incredibly powerful, yet last only milliseconds. First detected in 2007, FRBs have been traced to galaxies billions of light-years away, but their exact origins remain unsolved.
NASA research points to highly magnetized neutron stars, known as magnetars, as one likely source. Still, other bursts defy easy explanation, leaving scientists with a cosmic mystery that could reveal new insights into how the universe works.
