About this Image

Precessing-beam quasi-stellar object. The bright central component coincides with a Quasi-Stellar Object (QSO or quasar) at a redshift of z = 0.128. The QSO is precessing so the radio-emitting material which it ejects traces out an S-shape on the sky. The inset in the upper left of the image shows the resolution of the VLA observations.

Investigator(s):  J.J. Condon, H.S. Murdoch
