Images are presented of the starburst galaxy M82 from a 20-station global very-long baseline interferometry (VLBI) experiment 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 s-1 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. .
