The Algonquin Radio Observatory was one of the first areas to successfully complete a VLBI (Very Long Baseline Interferometry). Identical instruments were installed at the ARO and a smaller telescope at DRAO. These two combined signals would simulate a single 3,074 km diameter radio telescope. The recordings were made in the early morning of April 17, 1967, then the DRAO's tapes and atomic clock were shipped to the ARO for comparison. After a month of trying to get the data to "line up" they got success on May 21, 1967 showing quasar 3C 273 was less than 100 light years across, about 1/1000 the span of the Milky Way. :D Thanks for reading and viewing and feel free to like, comment or share. :D ©2013 - Wesley Liikane - Cowboy with a Camera
