The most distant object ever observed has been reported by M. Schmidt and T. A. Matthews of the Mount Wilson and Palomar Observatories. The faint (18th‐magnitude) object is a quasi‐stellar radio source designated as 3C147 in the Third Cambridge Catalogue of Radio Sources. The “quasars” are the most energetic objects ever found, and about a dozen of them are now known.
