  text: Over a dozen millisecond pulsars are ablating low-mass companions in close
    binary systems. In the original ‘black widow’, the eight-hour orbital period eclipsing
    pulsar PSR J1959+2048 (PSR B1957+20)1, high-energy emission originating from the
    pulsar2 is irradiating and may eventually destroy3 a low-mass companion. These
    systems are not only physical laboratories that reveal the interesting results
    of exposing a close companion star to the relativistic energy output of a pulsar,
    but are also believed to harbour some of the most massive neutron stars4, allowing
    for robust tests of the neutron star equation of state. Here we report observations
    of ZTF J1406+1222, a wide hierarchical triple hosting a 62-minute orbital period
    black widow candidate, the optical flux of which varies by a factor of more than
    ten. ZTF J1406+1222 pushes the boundaries of evolutionary models5, falling below
    the 80-minute minimum orbital period of hydrogen-rich systems. The wide tertiary
    companion is a rare low-metallicity cool subdwarf star, and the system has a Galactic
    halo orbit consistent with passing near the Galactic Centre, making it a probe
    of formation channels, neutron star kick physics6 and binary evolution.
