A class of object called a BL Lacerta object has no redshift, and remains a pinpoint of light on even the deepest fields, is thought to be a tunnel shot of the energy beam from the active nucleus of a quasar.

The knots in the energy beams emanating from the nucleus of 3c175 have been timed at some 225% the speed of light, were an observer to be looking directly into the jets, he or she would have found a BL Lacerta object!

A sequence of Very Long Baseline Interfereometry observations of the radio jet near the core of the quasar 3C 279, shows an apparently superluminal motion of 25 light years in 7 years.

The bright component at the left is taken to be the fixed radio core, the bright spot at the right appears to have moved 25 light years on the plane of the sky between 1991 and 1998.

Proper motions or upper limits, have now been established in about 33 objects, of which 23 are superluminal.

This phenomenon is relatively common in the nuclei of quasars, many of which exhibit systematic changes in images of their radio-frequency emission over periods of months to years, in some cases, features in the image appear to separate at a speed inferred to be more than 10 times the speed of light.
