Since the Kepler mission discovered extrasolar planets orbiting binary stars, we know that these circumbinary planets are relatively common. The scenario for their formation is however still unclear. Did they form in the perturbed environment close to their host stars or did they form further out and then migrate inwards? Solving this mystery requires detailed study of the morphology, composition, and dynamics of young binary-disk systems where planets may still be forming. We report the most detailed high-resolution images in scattered light of a new disk around a spectroscopic binary, embedded in a multi-stellar system. With a ring, a cavity and at least two spiral arms the disk's structure indicates possible interactions with close stellar companions or with forming planets. Our study raises additional questions that may be addressed with JWST and ALMA follow-up.
