Little did anyone suspect when the Bell Telephone Laboratories' "Sugar Scoop" antenna went online, as reported in this October 1960 issue of Electronics World magazine, that one of the greatest discoveries of the astronomy world would be made with it five years later. Developed originally to facilitate research on radio communications between the Earth and orbiting satellites, physicists Arno Penzias and Robert Wilson measured an unexplained level of background noise in the realm of 2.7 Kelvins that persisted regardless of where in the sky the antenna was pointed. After ruling out the antenna and receiver as the cause, they surmised that the noise must be coming from the cosmos itself, and that the characteristic of it agreed with the theoretical model of the universe at an early stage in Big Bang event. It is now known as the Cosmic Microwave Background Radiation (CMB, CMBR).

Someday ... World-Wide TV and Phone Calls Via Satellite!

A revolutionary means of telephone transmission was unveiled by the Bell Telephone Laboratories on the morning of August 11, 1960 - when a telephone call was bounced from coast to coast by using a 100-foot orbiting balloon satellite as a back-board.

A remarkable "sugar-scoop" antenna and the incredible maser were the key elements in this development.

November Electronics World takes you behind the scenes - shows you how these devices work, what they can and can't do, what can be expected from them in the future.
