There is compelling evidence that the recently discovered actinide superconductor UTe2 hosts a rarely observed spin-triplet pairing state. Here, the authors report the results of three classic low-temperature experimental measurements -- thermal conductivity, magnetic penetration depth, and specific heat -- in order to resolve the structure of the superconducting order parameter in UTe2. The results indicate a gap structure with point nodes, providing strong evidence for spin-triplet Cooper pairing in this material.
