Abstract: Until the advent of the large aperture VLTI and Keck Interferometer arrays in the early 2000s, long-baseline optical interferometry had almost exclusively been applied to stellar physics. Over the last decade, the range of astrophysical topics that take advantage of interferometry has dramatically broadened. At the focus of the 4-telescope VLTI array, the GRAVITY and MATISSE second generation beam combiners have enabled the observation of much fainter objects than before, as well as milliarcsecond spectro-imaging of complex structures at near and thermal infrared wavelengths. Furthermore, narrow-angle astrometry at an accuracy of a few tens of microarcsecond is now routinely achieved with GRAVITY. I will present a selection of recent astrophysical results from optical interferometry, and a perspective on future developments, including on the lunar surface.
