THE experiments of Bolton and Stanley1, and of Ryle and Smith2,3, using a radio interferometer have shown that a significant part of the extra-terrestrial radio noise is associated with point sources with diameters of less than 6 minutes of arc. Although the majority of these sources are unidentified with visual objects, their distribution indicates that they lie in our own galaxy. Attempts to detect radio emissions from specific extra-galactic objects have hitherto been unsuccessful. In this… Expand
