Images from the Pearson-Readhead Survey in Space, using the VSOP Space VLBI Mission

The images below represent 21 separate 5 GHz observations using the VSOP space VLBI satellite, HALCA, in combination with arrays of ground-based radio telescopes. This combination produces a "virtual" radio telescope with a diameter of approximately 30,000 km, almost three times the diameter of the Earth. Such a large diameter telescope provides higher resolution images than can be achieved with only ground telescopes. For each of the 21 sources below we compare the low resolution image made with only the ground telescopes (left hand panels) with the high resolution image made with the combined ground and space telescopes (right hand panels).

These observations form part of an effort by an international team of astronomers to image a complete sample of active galactic nuclei at high resolution. This team should be contacted for permission to use these images in presentations or publications.
