We present a new concept for the enhancement of heterodyne interferometry taking advantage of the frequency comb recently decorated with the Nobel Prize. The frequency comb allows stabilizing lasers to typically 10-17 surpassing the presently best such systems based on Cesium fountains. This will allow to stabilize the local oscillators in astronomical heterodyne receivers absolutely to a few times 10-4 Hz in the N-band. Independent frequency combs at different observatories can be used to stabilize CO2-lasers as local oscillators to port the idea of Very Long Baseline Interferometry (VLBI) from the radio/submm domain into the infrared regime. This could be the enabling technology for baselines beyond several 100 m up to many 100 km.
