MIT scientists pin down origins of a fast radio burst The fleeting cosmic firework likely emerged from the turbulent magnetosphere around a far-off neutron star.

Fast radio bursts are brief and brilliant explosions of radio waves emitted by extremely compact objects such as neutron stars and possibly black holes.

The team's novel technique might also reveal the sources of other FRBs.

MIT researchers looked to FRB 20221022A , a fast radio burst that was detected by CHIME in 2022 .

The light from the burst was highly polarized, with the angle of polarization tracing a smooth S-shaped curve.

This pattern is interpreted as evidence that the FRB emission site is rotating.

This suggests that the signal may have arisen from the close-in vicinity of a neutron star.
