The puzzle has been furthered by a repeated fast radio burst (FRB) with a variable, polarised magnetic field.
of what causes these mysterious millisecond-long radio wave bursts from outer space.
One of astrophysics' greatest mysteries since their discovery in 2007, FRBs have remained a mystery for many years.
They are very strong, producing as much energy in a split second as the sun does in three days.
While others repeat, some FRBs just emit a single burst before going silent.
Though one FRB has been found in our galaxy, the majority originate from faraway galaxies.
Despite the fact that nobody knows what causes FRBs or the highly magnetic neutron stars known as magnetars,
