  In astronomy, ultra-high angular resolution has always been a crucial tool for fundamental discovery. New momentum in high angular resolution astrophysics was provided by the millimeter VLBI system's Event Horizon Telescope's direct imaging of the vicinity of the supermassive black hole in the nucleus of the radio galaxy M87 and a number of pioneering results from the Space VLBI mission RadioAstron. The angular resolution was approximately 10–20 microarcseconds (0.05–0.1 nanoradians) in both of these instances. The requirements of advanced astrophysical research necessitate further progress toward "sharper" values of at least one order of magnitude at the level of one microarcsecond. The paper emphasizes that placing millimeter and submillimeter wavelength interferometric systems in space is the only way to achieve these higher values. In the context of t.. Read More»
