  Reentrant superconductivity is a phenomenon in which the destructive effects
of magnetic field on superconductivity are mitigated, allowing a
zero-resistance state to survive under conditions that would otherwise destroy
it. Typically, the reentrant superconducting region derives from a zero-field
parent superconductor. Here, we show that in specifically-prepared UTe$_2$
crystals, extremely large magnetic field gives rise to an unprecedented high
field superconductor that lacks a zero-field parent phase. This orphan
superconductivity exists at fields between 37 T and 52 T, over a smaller
angular range than observed in superconducting UTe$_2$. The stability of
field-induced orphan superconductivity is a challenge to existing theoretical
explanations, and underscores the likelihood of a field-induced modification of
the electronic structure of UTe$_2$.
