Abstract
THE remarkable observations of Cooper and Price1indicate that the radiation from the radio source Centaurus Ais linearly polarized and is subject to Faraday rotation of an amount such that: where nis the number of free electrons per cm3, His the magnetic field in gauss and α is the angle between the magnetic field and the line of sight. Cooper and Price assert that “the majority of the rotation must be occurring either within our own Galaxy or in the outer regions of Centaurus A”. Nevertheless they find that both of these possibilities are quantitatively somewhat implausible.
