Figure 2: Example illustrating how VLBI can produce ultra-high resolution images of the core of a radio source. This example show how VLBI can zoom into the very core of the giant radio galaxy NGC6251, at a distance of ~100 megaparsecs from Earth; the lower zoomed image is a VLBI image of the core where 1 parsec corresponds to ~2 milliarcseconds (1 parsec=3.26 light years).
Figure 3: Plot of the VLBI-measured distance between the Westford antenna in Westford, MA and an antenna in Wettzell, Germany over a period of ~10 years; the measured change rate of 17 mm/yr corresponds closely to the actual Atlantic seafloor spreading rate!
