XENON1T, the world's most sensitive dark matter detector, found a ~3.5 sigma excess of low energy (2-5 keV) electronic recoil events. This could be a first hint of axions produced in the sun, a nonzero neutrino magnetic moment, or absorption of bosonic dark matter. However, more mundane explanations remain possible, most importantly a trace of tritium contaminating the detector. I will summarize the result and discuss the evidence in favor of these different interpretations.
