    Images of the starburst galaxy M82 from a 20-station global VLBI experiment are presented with an angular resolution of up to 3 mas. These images resolve several of the sources into a number of components and with future VLBI experiments the expansion of these components may be tracked on a ~2 year timescale. Expansion of one of the brightest remnants in M82 has already been measured on a ~10 year timescale using the European VLBI Network (EVN) alone and an expansion rate of 10,000 km per second calculated. Furthermore, limits on the deceleration of this remnant have been deduced. Further VLBI experiments will be able to better constrain the deceleration of the remnants on a ~10 year timescale as they continue to interact with the interstellar medium in M82.
