Towards a Kilometers Baseline Interferometer

Frank Eisenhauer
Max Planck Institute for extraterrestrial Physics

Optical/IR interferometry has revolutionized astronomy at highest angular resolution and made possible transformational observations of black holes, exoplanets, young stellar objects, stars and binaries, microlenses, and many more. No other technique comes even close to the sharpness of interferometry. Here we present our thoughts on expanding optical interferometry to kilometer wide arrays, which will then be hundred to thousand times sharper than the largest single dish telescopes.
