Colliding neutron stars may be source of mysterious radio bursts.

Astronomers have linked fast radio bursts (FRBs) with the ripples in space-time emitted by collapsed, colliding stars. FRBs are massive blasts of radio energy that can outshine every star in an entire galaxy combined, while lasting just fractions of a second. The ultradense, collapsed cores of exploded stars (known as neutron stars) with powerful magnetic fields are the leading candidates for the emission of FRBs. However, recent observations suggest there may be multiple possible sources, which may include neutron star collisions.
