| | Abstract: The first successful VLBI experiments were conducted in 1967, just over 50 years ago.I will discuss the motivation for these early observation and their astronomical results as well as the technological developments that made them possible. I will also describe two of the most challenging VLBI programs being conducted today: the RadioAstron orbiting satellite,which enables VLBI networks with an angular resolution as fine at 15 microarcseconds at 1.35 cm wavelength and The Event Horizon Telescope (EHT), which is being used at 1.3 mm wavelength in an attempt to image the shadow of the black hole in the Galactic Center and and the nearby galaxy M87. |
