Abstract : The compact radio source in M 87 has been observed with a long baseline interferometer composed of the 210-foot telescope at Goldstone, California, U.S.A., and the 85-foot telescope at Tidbinbilla, near Canberra, A.C.T., Australia. The observations suggest that the radio source is remarkably concentrated to the galactic nucleus and has a linear diameter of about 2.5 light months.
